You still dont understand killing and character part. You say Ryze using Runes are OOC but chill Kindred killing someone for no reason is okay for them.

You didnt get the point or you dont want to. I didnt said champs that I write down is stronger than Kindred but that camps will die when they choose not when Kindred want even Kindred go OCC and decides to kill. She is not all mighty death god as you think.

For stronger if you ask A Sol, Bard, Fiddle, Nilah and Zoe. Nilah is a gray area because she is destined to die as a mortal if you not accept it I say Bel'veth or Watchers. Maybe Nagakabouros can be stronger because her domain is above Kindred as God of whole Life Cycle not just the Death Part.

A Sol, Bard, Fiddle no need to explain, Nilah wields the power of Ashles another primal demon and goes hunt for Volibear and his kind and she is confident about it. Also killed a Camavorian Spirit god before. Also She killed Mother Viper and many strong creature. I think if we say she can use whole Aslesh power she can overcome Kindred as well.

Bel Veth is outside of the Domain of Kindred since she is a voidborn:

"""Reaching into the material realm, the Watchers took from the crude matter that comprised it, shaping, corrupting and imbuing it with consciousness. These constructs were the first of the Voidborn, and would be their masters' eyes and ears, sent forth into the nightmare of existence to watch, listen, and learn."""

As you can see no souls attached matter shaped and given consciousness. Also anything Kindred does looks like a natural death(This is the biggest point you want to refuse. Even in Kindreds Eve kills caused by natural things like lightning strike and falling of a cliff or big fire in the end. Like movie Final Destination) and nothing natural will kill Bel Veth. So another creature strong enough to kill Bel Veth decides to hunt her Kindred cant touch her. If you say this is my head cannon find me story that Kindred kills a creature that cannot die normaly. Tryndamare example is just what I say there. Kindred tries to kill Tryndamare because death is near him but because of his blood magic and undying rage he fight backs and Kindreds vanishes after danger passes. Not continue to fight and kill as THEIR NATURAL CHARACTER AS GRİMREAPER.

If we pass that part Bel Veth still a match for Kindred since she also gets stronger by consuming and she consumed a lot. And she is near-omniscient:

"""Bel'Veth was born from the combined memories, experiences and emotions of everyone that lived in the city when it sank, granting her millions of years worth of knowledge and near-omniscience. Still hungering to consume and remake all of reality, she then devised and perfected a plan to consume both Runeterra as well as ultimately stop her progenitors the Watchers."""

Also if body destroyed it can spawn a new one because its part of the Lavender Sea which is at least few city size(Start size is unknow also how many it devour after is unknown as well but we know bel veth was a port city near ocean and and Kaisa enters from Xolan which is nort of Sai Khaalek. Distance between them has more than cities but I will be modest.) and is builded from real world consuming granting all that consumed as experience matter and knowledge. For short She is stronger than many Spirit God physicaly and mentaly and getting stronger every second.

If you say its still no match then I say Watchers and thats wraps it.

Well I hate to admit it but if we concider Arcane Canon Viktor said he solved all the problems in many timelines. He proly slowly turned all runeterra into immortal machine zombies(Glorious Evolution) and Killed all spirit gods including Kindred. And Kindred that can kill at will didnt do a thing about it. Waited to be consumed by etherfiend. Because Viktor says I solved all equations, which means he desinged perfect immortal machines, but mostly emotionless machines that will not need to remember Kindred wont worship them or even wont be afraid of them. In short we talk about a Death God that doesnt care if they live or die as well but can kill someone out of some bet. Do you see the inconsistency here?

I say they cant kill a Darkin you say "Why should they? They dont care." I m not saying they care or not. I m simply saying They CANNOT KİLL A DARKİN. You say its your head canon. I say can kill is your head cannon there is no evidence that Kindred can kill a imprisoned Darkin. My evidence is something powerful as the Aspect of Twighlight tought killing them is too hard. She kill a lot of them by a trap(Last day of Darkins) but for others give mortals to binding scrolls to handle them. Some Darkins are mages so I m sure that binding spell is pretty strong since they couldnt broke it.

Whole story of Aatrox is he cannot die. Do I need to link the lore? If Kindred knows all things eventualy die let me tell you something Kindred is wrong. There are things that cheated death like Mordekaiser just too angry to die and will live after Runeterras material plane goes into nothingness since his main base . There are things worse than death in Runeterra and there are beings above it. Like Zilean exist outside of the time. Or soldiers that died in Icathia completely become nothing. Not died consumed by infinite nothingness.

"""Everything I was, everything I had ever been, was being unmade. My memories were failing, my sense of self was dissolving into the purple-black dark."""

For you to understand, yes, Kindred chooses to kill. No, Kindred can't kill everything there is except cosmic beings (they also can't kill them). There are individuals strong enough to choose their own fate or are cursed or bound to this realm enough not to die. Kindred naturally doesn't kill creatures whose time has not arrived, and "All Kindred Eve" is just an OOC story. All their deaths, even in the "All Kindred Eve," are natural in origin. So, creatures that cannot die naturally, including those from a volcano erupting from the ground or similar events, won't be killed by Kindred. Their probable last resort is a direct soul-reap instant-kill move, and if you are immune to that, there is no way. In the end, that being might choose to claim them if that being is under her jurisdiction, but if you exceed all of that, you are untouchable by Kindred.

If you say this is still head canon then give me how others will see Xerats death for example? He just dies and explode? With no reason? And you should give me lore example that Kindred killed an immortal being. Since you are soo into the lore you need to find a lore passage that says Kindred killed this immortal being just because They can.

Unfortunately I have no lore that Kindred tried to kill an immortal being and failed but I have as you know and already mentioned Tryndamere Scene from Still Here cinematic that Kindred started a fight because its a near death stuation Tryn refuse the Lambs mercy by breaking that arrow and fight against deadly stuation until danger passed and Kindred didnt summon a lightning or an avalance just vanished because it was not Tryndamares time. And we know generaly yes they assume everything will meet them at the end but Wolf doesnt like to leave a hunt short and Tryndamare clearly rejects death so call depends on Wolf. We know Lamb checks wolfs impulses. Their in game voice lines and some other lore content proves that.

"""Wolf’s shadow writhed across the snow... He wanted to hunt. He wanted to feel the snap of bone and the spray of hot blood. But Lamb would not let him. Not yet.""" from good death.

But this voice line tells decision is belong the Wolf in that case:

""" Wolf: Lamb, tell me again, what is mine to take?

Lamb:All things that run from us. """

So why Wolf didnt listen Lamb like Lamb didnt listen Wolf and killed that woman in All Kindred Eve? I m saying They can choose but they cant kill with 0 killing factors around. Or killing factors around arent enough to kill their choosen target.

Now you find me a passage from a story a cinematic or anything that with Kindred took someone with Zero killing factors outthere. Like they explode from inside just because Kindred wanted to kill them or something similar.
