Ask my antagonist anything

Hi, this is my first time doing something like this so bear with me if I dont do everything right. Im doing this to help me come up with dialogue for my antagonist (poor man does not even have a complete character page).
Some rules:
-Please don't ask anything NSFW
-Have some patience while I answer the questions
Some background info:
-My antagonist name is Arcadio Vitamre, but his alter ego is called the Owl
-He has two kids
-He's 40
-He's into some shady cult that wants to kill gods

Why is he drawn to that god killing cult? Did past experiences make him feel that way or is he simply curious?

(sorry if this question is too complex idk i'm just super interested in your last point lol)
