Will me being infantile stop humans from hurting each other? If not, why would I be motivated to change?
Will me growing up (to stop being infantile) get in the way of my refraining from hurting others? If yes, why would I be motivated to change?
In my infantile state, I can clearly see that - even in a complex world - harming other living beings is wrong. I don’t like being harmed, so why would they like being harmed?
Maybe you need ideology to simplify the world. But that doesn’t mean that I require it. That’s part of the complex world you assert we live in, yes?
