Can a person's free will be a causal factor in their choices?

To illustrate the question I'll make a comparison: a chess player is not a causal factor for a chess piece moving from position A to position B. The piece moves because the player made a decision and executed a move. However, the decision was made based on the current position of other pieces, and the outcome is determined by the rules of the game.<br><br>In a different scenario, a person makes a decision and executes an action that leads to a particular outcome. But was the decision a result of causal factors such as genetics, upbringing, or environmental influences? If so, was it a causal factor, or was the outcome still a result of the person's free will?
