Punishment

The 8th amendment is necessary in our legal system, but i think it needs to have more details to it. People deserve punishments for doing wrong because it makes them learn. But sometimes people take actions too far like murdering some one. I think cruelty is necessary if a person physically hurts or even kills some one. I think they need the 8th amendment to clearly state what constitutes cruel and unusual punishment or else people will maybe do things they shouldn't be doing...punishment wise.
