If they let Loki die, then it be sending messages about ruling humanity with a straight line, iron fist. Chaos brings flow and grow. Nothing in nature function in a straight line. Not even humans. When chaos happens, we go with it . After, we let it go. Also letting the idea black sheep is bad to be good.

Letting Thor die, that's sending messages let injustice thrive, and humans continue to be sheep to the narcissist society.

Bull!
