People will do "evil"(as harming allies) if:

1) they are unsustainable (like harming allies) - not sure can be fixed

2) Don't have enough knowledge(broken perception) to do differently.

3) ROI of doing evil is too high.

etc.

Could you point to scenarios where aknowledging non-existence of free will could help us? IMO it doesn't matter.

EDIT: Actually I think that existence of concept of free will is positive because it makes people compute choices better (even assuming free will does't exists and computation is deterministic)

The understanding of free will is an illusion has brought clarity and forgiveness into my life; towards all the persons who wronged me. I became aware to how it would be irrational to seek revenge of some sort against persons who deeply wronged me to disfigurement.

Short summary: I’m transgender and couldn’t transition when needed and to live a life of less pain because of others.

Arareness towards understanding people are who they are without any control brought me to realizing “who the best me would be” in the current situation. A person who cannot blame directly the person who wronged me. I might end my life by suicide though. So the impact of what others did to me was great and I still trumped it.
