I agree that some innocent people are put to death, which is why I am probably more against capital punishment than for it.  However, the level of violent crime and the nature of violent crime in my country has gotten so utterly disturbing that I can´t help but agree with Daydreamer....why should we keep these people alive? 

 You can lock them up forever under strict conditions - seems to me more punishment. Besides I don´t know if it´s true but I´ve heard that death penalty including all the trials, the lock-up, the execution etc costs more (because at least in the US it can take many, many years) than sending someone to ´life´.

Edit: the main reason for me to be very, very against it is that I think that no-one is allowed to take one´s life. It would be like sitting on the throne of God, and hey, I´m an agnost, I don´t know if s/he excists!

On the second thought, I might be against capital punishment if its alternative was hard work for the society not lifelong free food and sports facilities. Unfortunately it is illegal to  force somebody to work and we end up with criminals who are unwilling to change and spend their life at our cost.

 This is a disgusting statistic in my view, when you look at where the most executions takes place and realise that many of those being executed are for political reason (China in particular) and in places like Saudi and Afghanistan it is for simple "crimes" where people are execute for adultery.  And has it not been proven that the death penalty does not deter serious crime? 

 thats one of my thoughts that makes me go against the death penalty.
