In my opinion, most aren't, they get a free ride in prison and although the situation changes when they are released, the endless opurtunities for attributes such as education can't be denied - also, are many crimes such as murder punished accordingly? Should we stick to the old rule of 'a life for a life' or are the members of this forum more inclined to give 2nd chances?
What about the innocent people who would be executed as a result?
but by killing them, aren't we as being as bad as them?
crimminals describes many people guilty of many different things, certainly prison is harsh enough for people who dogde tax, nicked tvs to fund the drugs habit, is what u are asking more to do with serious crime like rap/murder?
