I think there really might be a route to disproof evolution if you can proof that true unecessary evil exist.
And an unecessary evil would be to experience free will while it is not there and in reality good for nothing.
Similarly you do not need a conscious experience of pain to avoid pain, you just could programm a computer to react to the pain signal coming in over a certain nerve fiber (philosophical zombie with pain reflexes)
Here you can see what the atheist thinks the illusion of free will is good for in evolution (so that the problem of unecessary evil does not arise):
The most funny highlight of the text:
"First, I bet it’s untrue that no one has given a good explanation for why evolution could have selected for the sensation/illusion
/experience of free will; I think it’s much more likely that these commenters (that don't see evolutionary explanations) simply haven’t read those explanations. In their defense (of that comentors that can't find such an explanation), though, I have read a decent amount on this topic and haven’t seen a good explanation either.
That made my day
The alternative explanation given in the text is not good either. Firstly animals that seem concious (mirror experiment) do not necessarily form societies.
Secondly "moral blame" as every computer scientist should see quickest is just a sort of reward system that could be substituted through a non-conscious reward, such as giving a certain brain area more energy when it engages in social interactions. You hence do not need to be conscious or (wrongly? as an illusion?) assume you have moral choices to build a complex society.
