I've actually seen a video that said "no one is born evil" once on Youtube. I was more of a fan of TLK so I came upon a video about Scar/Taka and found that wording. And of course, that is in fact true.
I have a character named Pierce who looks kind of evil and he is evil, but he is just albino and that's the way he was born. I also have a character named Shadu who is pure black with red eyes, but his pelt did have his pelt changed, just through a small story of my made-up weirdness. XD I don't play him in which is why I deleted him, but whatever. He can transform in and out of pelt colors though.
I always make pasts for my characters and evil characters of course, and they are never born evil truly. Havor was born with a strange personality that led him up to becoming a killer. He wasn't exactly born evil, either. He just made mistakes through his past that led him up.
Ahh, what I'm saying here is, I understand you. >_< Also, Tariri, not all children, as you can see what I wrote here.
Though I have to agree with you there, those gifs explain a lot most of the time.
