@Thighs4Life the npc would probably blame himself, seeing how kind he is. He'd probably think he accidently fucked up a sacrifice to gain a blessing and killed someone for no reason. Or maybe he would think the blessing is just in disguise and if they didn't have it , then it would be worse.
@bobthepusslayer the widely accepted option would be the previous world continue to exist. Meaning there is more than 4000 space-time continuums where he suicides himself but mathematically it doesn't mean anything as there is infinite multiples of himself living on.

"Your skill is probably magnificent as well"
"What a cursed, wretched world we live in"
"I think what's actually cursed is your intelligence"
