You don't even know his comics biography and you're demanding that. 🙄

A few seconds at Wikipedia could tell you his basic motivations, which are not terrorism:

Raʼs al Ghul is an international criminal mastermind whose ultimate goal is a world in perfect environmental balance. He believes that the best way to achieve this balance is to eliminate most of humanity

He's not trying to scare anyone, just kill them and everyone they know. He doesn't care whether or not there's any terror. It doesn't even enter into the equation for him.

The fact that you don't even know that and you've been arguing with me this whole time about him being a terrorist is hilarious.

Next time, maybe learn about Batman before you argue about Batman.
