I’m really surprised no one’s mentioned this yet. Thanos has a reputation for taking vulnerable youths and twisting them to become his weapons.
The people he considers his “daughters” were tortured and manipulated into carrying out his orders.
In Avengers, Loki is clearly in the same boat. He’s been tortured into obedience.
It’s a recurring tactic Thanos uses to gain allies.Ive….mentioned it many times lol….. check my meta tag…..
