I remember speaking to two brothers at different times; one was abusive to his girlfriends, the other kind. The abusive one said he was abusive to women because he grew up seeing his dad beat his mom and that’s all he knew; by watching his dad. The non-abusive one said he grew up watching his dad beat his mom and all he knew was to not be like his dad.
I think the problem with your computer analogy is the computer has no choice but to react to its input because it is incapable of making a decision. People are different; no matter our heredity or environment, we can still choose to do differently because we are capable of making a decision.
Nils wrote: Ken,
Are not computers making decisions?
No; computers only do what they are programmed to do. They are incapable of independent thought.

The computers on self-driving cars are programmed to react to the sensors around the car. They do not decide to react to the sensors, they have no choice; they can only do what they have been programmed to do by an outside source (programmer)
People are different; though our decisions may be influenced by circumstance, experience, or outside sources, they are not determined by them.
Computers do not only react on sensors, they also relate to their inner states, just as person do. Do you have another definition of “decide” than the standard? Se for example
https://www.merriam-webster.com/dictionary/decide
“decided; deciding
transitive verb
1 a : to make a final choice or judgment about
• decide what to do
• couldn't decide whether to take the job or not
b : to select as a course of action —used with an infinitive
• decided to go
c : to infer on the basis of evidence : conclude
• They decided that he was right.
2 : to bring to a definitive end
• one blow decided the fight
3 : to induce to come to a choice
• her pleas decided him to help
•
intransitive verb
: to make a choice or judgment
• decide on where to go”
This definition applies to computers as well as persons ( even if the examples are related to humans)

Then you say that we can choose, "no matter our heredity or environment". If you include some randomness, it seems that you refer to some forth factor not included in the three I mention here. What is this?
Free will. The ability to conjure independent thought; and act on them.
What is “independent” thought? Independent of what? In heredity and environment is usually included everything that follows internally from the environment for instance you inner states, desires, beliefs, preferences, views, decisions. Environment is everything you have experienced and all external forces including God (if you believe in God) that have acted upon you. This is independent of if you believe in a spiritual part of you or if you are a materialist. Even a spirit is ruled by causality.
I admit that there are philosophers that not only think that there is the standard “event causality”, that events acts on us. They also believe in “agent causality”, that the agent (undefined) as a being outside time acts on the physical (or maybe also the spiritual) body at specific times. However, this view is highly speculative and there are lot of problems with it and it is commonly regarded as untenable in philosophical literature.
