death penalty

I personally think that the death penalty has more pros then it does cons.

Pros:
gets a convicted murderer or rapist off of the streets for good with no chance of escape or coming back.
the tax payers do not need to pay for the convict to have three meals a day and for the general up keep of the persons living conditions until time of death.

cons:
It is murdering someone for murdering someone which follows Gandhi's saying, "An eye for an eye makes the whole world blind" which to me is making the supporters of the death penalty openly and support the death of every inmate sentenced might make the person as worse as the murderer, morally.

I think this brings into questions is one mans death necessary for the good of others effected by a serial killer? and if we can morally carry out this sentence.  From a money perspective I honestly rather have the government pay for one lethal injections rather than hundreds of meals for someone who may just die in prison never actually leading a life outside of prison for years.  From a different perspective i also think it is wrong.  I guess it depends on the situation. Boggess seems like he has changed however he did murder two people for money and admits that he enjoyed it I cannot really chose a side because of my conflicted beliefs in the matter.
