The Death Penalty is known as a punishment made by the man to make another man pays for the terrible things he had done.
It consists on inducing the death. the sinner is injected with a mix of chemicals that makes his organism colapse.
the thing is that the society limits thelife of a human being, judging against a "wrong act"... but what its wrong or right? we are dealing with the LIFE!
the Death Penalty can't stop the crime and can't change the criminals... its totally negative. It can only satisfy the feeling for revenge from the victim's family.
We are in the 21st century.. its a edge of technology, advances and culture.., but we still haven't get the real meaning of being alive.. the sparkle of life!
it's something really arrogant determine when someone has to finish their existance in our world. above this principles, it seems that is more consistent give effective faults (all life in jail) than trampling on the will of our gods.
in conclusion.. I think that every person can change, can be a better man or woman.. the thing is we have to give this opportunity to change, no matter how big the problem or the sinn was.  in a deeply corner of our souls he have the chance to be developed to a great person. the Capital Penalty destroyes this chance. " A penalty of this nature is not a corrective, it can only be an act of revenge"
