I don't believe in free will. Every decision we make, we make based on our personality, state of mind and circumstances, and our personalities are shaped by our genes and the environment we grow up in, two things we have no control over. You might say: "I'd never hurt anyone", but if you were born and raised under circumstances that lead to you having a personality of a serial killer, then that wouldn't be true anymore. I cannot take credit for not being a rapist or a murderer. Instead, I say I'm lucky not to have been one.
I'm going to take a leap here, and totally take credit for not being a physically abusive mother.
I was completely raised in the sort of environment that should have created an abuser in me. My sister is abusive to her children, I am not. I restrain my anger, even if I visualise hitting them, I don't. I chose to do that.
Nothing differs in mine or my sister's upbringing, same parents, same abuse, same schools, same shaping of values in children's home when we left home. She beats her children, I do not. That is my free will.
To say that was nothing to do with my choice, is to make the actual choice I made...logically, with thought (as in I spent time thinking about it), away from me.
I just think it's not quite right to say no such thing as free will exists. It is like giving up agency over oneself. I can't allow myself to give in to that way of thinking, because then I have nothing, nothing whatsoever to be proud of when I choose to do something and accomplish it, I can't even take credit for it. :/
