Absolutely. I think we should still encourage good behaviors, while at the same time remembering that we merely provide a different perspective that takes time to bake in.

We cannot expect someone who is broken or taught wrong to flip a switch and become good out of sheer desire to be so.

Taught behaviors take a long time to change, this is just how neurons operate. With enough time and positive influence (including positive example), a person can retrain themselves to do better. Besides, to do so, they should first know for themselves what is right and what is wrong, and your perspectives might differ.
