free will

I will use the difference between a person and environment and Karma to explain what I believe about this topic. I will give the short version.
A person vs Environment: Human being is the only creature that is not 100% reactive to the environment (like plants) or to the perception of their environment (like animals). Human being has developed a neuro psychological bubble that separates human from its environment. This neuro psychological bubble gives human a DELAYED reaction to environment. The question is not if this is free will. The question is how free is this free will. First, our ability to delay a reaction is affected by our biology and emotions. I think our plasticity of our "free will" depends a lot on our sense of pleasure."it is easy to be nice when you are happy" kind of thing. I like and will use @Lucia's term "Skills" in how easy this skills deteriorate as our sense of pleasure dips. Craving is a good example of this. Second, this ability to delay a reaction gives us little bit of control of our environment. The key word is little bit. We can't control weather but we can manage an emergency measure to deal with it. However, we mostly still don't control our environment. We rely highly on "Trust" in our environment, man made or nature made. I drive my car everybody thinking everybody knows how to drive and is in the good condition to drive. There are thousands of virus in the air and in our body that can defeat our immune system.
