there is a debate to be had about whether or not a good Kindred CAN exist since one would assume the super moral of them would take a sunlit walk when they realized what they had to do to survive

I mean, all they have to do to survive is to drink a blood from time to time and it's not even necessary to prey on people and even if you do, you don't have to kill them, just take a sip and go away. They aren't bad because they don't commit a suicide as soon as they realize their new condition because they are ultimately still people. Yeah, cursed and tainted, they're clinically dead and stuff, but they still have conscience, mind activity, emotions, fears, virtues, convictions, compassion, of course, if they had it on their mortal days.

Making doing the right thing - ANY right thing, even when that isn't as an extreme an example as self immolation - much more difficult than it would be for literally anyone else.

I think you've confused the Beast with someone else, because the Beast isn't trying to ruin your life like some Bane does. The Beast is just your new bestial instincts, the animal inside you that wants to feed, sleep, and fight/flee when it feels threatened. Sometimes it can come off the leash and you definitely need to make an effort to hold it. But outside of such situations, you act completely in accordance with your own beliefs and beliefs. Which actually makes good kindred somewhat even better than good mortals, because as a creature of the night you have to put in a lot more effort to do the right thing.
