@icedquinn basically in my world it's on the brink of total entropy to where nothing new will ever happen again and my villain have basically seen that it's futile to trying to convince people otherwise and he's essentially using his ability to control life to rapidly Force rapid evolution on everything that it touches basically like a plague being unleashed hoping that he can essentially Force a new existence of chaos to avert entropies eternity.
There's a lot more complex stuff but this is the most simplistic kind of detailed reason as to why he's doing what he's doing.
