A more important paradox is the illusion of free will in a deterministic world. Yet at a closer glance this does not seem to be a real paradox either -- it is based upon another fiction; that is, that people have free will. People can "choose" on a whim to act a certain way.
I haven't heard any convincing arguments resolving this paradox. There is no easy answer. Compatibilism essentially says that lack of ultimate freedom to choose "doesn't matter", but clearly when you are morally blaming people for actions which they were completely compelled to do, it does matter. It's hard to understand why the compulsion of a gun to the head is more meaningful than the compulsion of Hard determinists hit closest to the truth -- and the main argument against them is seemingly that they are "too pessimistic".
People should be held
The the perpetual "free will" illusion has a pragmatic, self-fulfilling - when everyone believes that everyone has free will and that people who commit wrong acts do that willfully, it imposes a deterrence on immoral and criminal acts. Lifting the veil could potentially revoke that deterrence and allow people to act even worse than they currently do, if you can imagine that. But is that really likely? I don't think so. The deterrence does not seem to be very effective. The veil, as an obvious fiction, is already under subtle attack and has been since the beginning of human history. The distorted view of responsibility confuses people. The first step to recovery is to stop denying.
Some people may think Social Darwinism when I say genetics. While that may be a concern twenty or thirty years down the road, I don't mean to endorse that view at all. The study of how genes affect behavior seems like it always be an imperfect science because of all the variables. Furthermore, if someone is told that they are genetically dishonest or sociopathic -- is it possible for them to then consciously overcome that? I don't know.
Some may notice that this argument is essentially just a secular repacking of Calvinism. Just as Calvinists felt heavy pressure to prove themselves as God's chosen, so people today may feel the pressure to prove themselves as good genetically.
