Can people turn to undead if they want? (Kindred-Karthus related theory)
" Embracing life means accepting death. "
It's what Lamb is saying. So if you don't embrace the life, you can't accept death neither. You become a entity who is between living and dead.
If a person who wants to throw off his life kill himself does he turn to an undead? I don't think it always happen for the order that's because there will be always people who want to suicide and I think it is valid for Runeterra too, so it requires a lot more things. But it's still responsible reason to get it to case. That's the substance can make strong my theory:
Karthus always wanted to embrace death and hated than his life since childhood. He always thought about how dying would be awesome, seeing himself as corpse would be a pleasure. He even made a fake funeral for understanding and feeling this moment but it caused him to become isolated by his people. Then he wanted to die in Shadow Isles, but with some undisclosed case he became a lich, a type of undead.
Don't get me wrong, I'm not saying it's the only way to become undead. A curse, a rituel, a powerful entity can turn a living thing to undead I believe. But it can be one of the ways to turn undead.
Sorry for bad english.
