Of course it is. Some people just do stupid things. I bet that most of us have done something stupid in our lives, whether legal or illegal. Some of us were lucky and suffered no consequences for our actions, whereas others were not. But there is no need to go on punishing someone forever. Once their sentence is over, the state has effectively certified that they are ready to return to society. What is the point of ostracizing them even more? What does it accomplish?Don't like that? Don't do it in the first place. Stupidity is not an excuse.
