I believe we have free will when it comes to our decisions, and if you don't you are opening up to arguing that if people do not have free will, then everyone is not responsible for their actions, which we are. Obviously there are factors, and I wouldn't disagree that the environment you are brought up in/ are in, affects how you would approach certain decisions along with many other factors such as:

Health, (both mental and physical)
financials,
personality,
morals,
religion,
family,

You could use these factors and the data that comes along with it to predict what certain people may or may not do in a situation however, if you get it right it doesn't mean free will doesn't exist, or your a god, it just means you have predicted and analysed the situation correctly.

My main issue with the argument of no free will would be the fact that if you believed in that you would have to argue that murderers and other heinous crimes are justified because the perpetrator simply had no choice, he HAD to kill those people, its not his fault.

Throughout writing this, I have argued to myself that you could punch someone in the face at any point in the day if you wanted to, but you don't because you don't want to. Maybe that's because you aren't aggressive or you are scared of the repercussions, it could be anything, but maybe that "not wanting" to do something even though you could do it at any point, takes away part of that free will. But even then with that thought it would still argue that free will is real, it just gets hindered.
