The Death Penalty

The issue of murderer's punishment is one of the most difficult and problematic. Lawyers of all time as well as different human rights defenders have been discussed it from the introduction of criminal law. Needless to say that they can't agree on whether it's better to punish murderers with death sentence or to send them to the prison for whole life. From my point of view the death penalty is the most convenient way and next I'm going to give some reasons for my opinion.
It goes without saying that when the state send criminals to jail, their living there is provided by common citizens, who pay taxes to the state's budget. Besides, the fact of their almost carefree life definitely causes pain to the victim's relatives. And we shouldn't forgot about them, because usually when someone expresses the opinion against death penalty, arguing that it's very painful for the human, he/she doesn't think about the closest ones of murdered person at all.
Furthermore, the opinion of the society's guilt of commiting murder if we choose the death penalty seems to me very questionable. It sounds like the murderer can kill any person and we shouldn't do nothing with it but make up mind to it. Why? Because we can't take charge of "murder" of guilty person, we don't want to see ourselves as gods, but then criminal is considered to be a god, because he can decide who will live and who will be killed.
Taking everything into account, the problem of death penalty seems to be insolvable. The arguments of both sides are strong. And it's really hard to decide whether the society has a right of justifiable "murder" or not.

The penalty ( punishment is not correct in this sentence) for murder is a difficult and problematic issue. Prosecutors , defense lawyers (lawyers are on both sides of the issue and should be distinguished) , as well as human rights advocates have been debating this topic since its inception in jurisprudence ( inception is a better term because it implies beginning and introduction implies something from the outside coming in // jurisprudence is the better term other than criminal law ). Needless to say capital punishment  ( death penalty is an ugly way of saying it) or life imprisonment are the dilemmas faced. I favor the death penalty and these are the reasons why (always own your personal views). The penal system is supported by taxpayer funding and in many societies the inmates live a carefree life that deepens the pain of the victims relatives (it goes without saying is incorrect because it implies a known fact when actually it is your opinion and there are many who might not agree with you). Those who advocate against the death penalty often ignore the pain of those left behind in their zeal to protect the perpetrator from  the suffering the  death penalty  (you see how I reworded it to make your thought clearer). The opinion that instituting the death penalty creates societal guilt is a dubious assertion (furthermore is only used as the very last comment ). But many feel that a murderer should be given a penalty as severe as the murder they committed. Why? Because they feel that even though they might believe only god should take a life, they feel if they do not then the criminal takes the position of god by deciding  who does or does not deserve to live. Taking all this into account the issue (it is not a problem) of capital punishment seems to be unsolvable because both sides have strong arguments, making it hard to determine if  state sanctioned murder is justifiable.
