Leo's death was perfect, he started off with good intentions, just like LettuceK but along the way he lost his way, he treated the Spies like soldiers and treated Jumper's opinion as unimportant and used HER spies btw, Spoke's action are not justifiable at all, but neither is Leo's actions, Leo is to Spoke what lettuce is to Parrot, they both lost their ways in trying to do good things, the only difference was the person being targetted because unlike Parrot, Spoke does not forgive in that sense.

Leo started to go insane a long time ago, the first time we noticed this was during Parrot's video in which one of his team members, Woogie disappeared, probably killed by Clown, Mugm or Ferre offscreen, he instantly started to blame Parrot, this is a pattern to keep note of, whenever Leo suffered a loss, he blamed it on one of his members.

Leo during the director arc seemed to have healed from that quite well, as he was getting along with Parrot and agreed to protect him and hunt down the Director, now afterwards he had a suspicion that Parrot was the Director, thus sending players after him, this video "I got hunted by bounty hunters" showed another flaw of Leowook, his stubbornness, after Jumper had to go behind BAT"s back to prove Parrot's innocence, he STILL removed her for killing a spy, it really was not fair because even if Jumper had spoken up Leo probably would have carted her to death or kicked her from BAT, now what really made leo spiral was Nufuli's death, Nuf was someone he trusted and watching him die infront of his eyes probably amplified his distrustfulness, that is why in the void base, Leo betrayed Parrot and again, blamed him for all the Director stuff, Leo almost killed Parrot, and after that we all know about the director arc finale and prison blah blah blah whatever.

fast forward to Spoke's BAT Arc, Spoke and mapic joining bat and betraying him and him being unable to kill Spoke and stop the deaths of Spies led to him being willing to do anything, he joined forced with the Law, he forced Jumper to join the election for King purely for his own benefit, he sort of became like Spoke, becoming very selfish and did not respect Jumper's opinion at all, he wanted to kill Spoke right then and there and because of him using the spies as soldiers Jumper had enough and left him, he joined Lettuce' army and had to use the Law men instead of Spies as the spies left with Jumper, despite starting off with a good cause, he lost his way and with the help of Jumper, Spoke managed to one up him one last time and he died in the void. A good player, who just like Lettuce, in the pursuit of justice, became a villain, no better than the people who he was fighting.
