Free will is the English translation to liberum arbitrium, a concept that philosophers have never trivialized.
It's something very complex: it's the capability to do what you want to do, but in the context of an universal awareness.
Universal awareness is being aware that we, as human beings, have all legitimate desires and aspirations.
So, if my desire doesn't harm anyone, it's legitimate. Because it doesn't harm another's freedom to choose.
Sounds like you're getting into ethics, not the factual question of whether human beings have free will.
