theres a bunch of suicides, as styles i mean, they are not all equal, you got Hannibal's Suicide, so thatt he romans couldnt get him alive, you have 'regular' suicide, when person is not happy with his life, mostly he rather be dead than alive, normaly to end some kind of pain (i defend that people have the right to euthanasia), theres suicides like the Columbine guys..i'll quote from a familiar gun game Unreal Tournament, those suicides are known as God Like, where you immortalize your doing by it, which carries the message you want to deliver...and you must agree, those guys are immortalized, theres even a great movie called Elephant, theres references all over the world, etc.
How i and most people around here see death penalty: the law isnt enforced, the criminal isnt being led to justice, what happens is that you take another life, and the criminal isnt making up for the crimes he commited. A reasonable way of putting him up his crimes is to lock him up, even if its till the rest of his life, with hard labor or whatever. Prisons being comfy or not, it's not the questions, a prison is to lock people that are a threat to others, normally taking away the rights and needs of that person, so he's exactly excluded from the society, he isnt free, thats what matters. If you lock a person to the rest of his life in a prison, that person wont kill again, no need to end his life, everybody has the right to live, even those who dont have rights like others who are in prison, life is an human right. Whenever you kill someone you'r violating the human rights, why do you think saddam was accused of violating human rights? Still he claimed innocence, since those who he killed were (for them) criminals, so it was like the american death penalty. To die/death penalty is to free of prison, plus it's against human rights, thats why we dont have it.
This issue comes with gun control, we dont have guns, because guns are made to kill, baseball bats are made to play baseball, knife are made to slash or cut things, not necessarily people. Can you play baseball with a gun? or cut things? Only thing else you can do with gun is shooting sports (i love this winter sport called Biathlon), and hunting, excepting for shooting sports, guns are made to kill, plus the guns in those sports are slightly different from normal rifles.
