I disagree with your inclusion of that graph as evidence.
1) It's only the trend in one country - the US. There's absolutely nothing to compare it with. Perhaps the world just got more violent at that time, and it was coincidence. We don't know.
2) The amount of executions is tiny. It's hard to draw a conclusion from such a sample.
But most importantly, it doesn't contrast with my claim. I posited that capital punishment is not that much more of a deterrent than life imprisonment. The homicide rates in a wide variety of countries had no signifiance variance whether there was capital punishment or life imprisonment as the penalty for murder.
Yours, though, merely demonstrates that the more often executions occur, the less like murder is to happen, and vice versa. I never questioned that executions were a deterrent to murder, which is all that your graph demonstrates. It's obvious that it would be. However, there's no comparison with life imprisonment at all.
Your evidence is tangential to the topic.

And let's not forget that murderers can still murder even in prison. You're accomplishing nothing by keeping them incapacitated for the rest of their life, which I would consider far more cruel and unusual than execution. Given the choice of life in prison or the electric chair, which would you choose?
You're assuming that murderers are murdering machines. They're not. The majority of murderers do so in passion - they just can't take their wife cheating on them, or their ****ed boss just won't stop forcing them to work overtime, or whatever reason they have for it. Not many murderers are serial killers.
In answer to your question, I would prefer life imprisonment. Better a life, than no life at all. And that's what we're doing by keeping them in prison. Preserving the sanctity of life.
Finally, what about the incurably insane? People who have to be kept in asylums for their safety? Would you want them to be killed, rather than kept in what is effectively a prison for the rest of their life? Which would be the more cruel thing to do?

If someone makes a rational decision to end another human being's life, then they automatically forfeit their right to life, liberty, and the pursuit of happiness by virtue of taking someone else's away.
Philosophical and moral implications aside, I doubt you would advocate letting people go unpunished for their actions.
You aren't explaining why, though. What's wrong with a lesser punishment? Why do they have to be killed?
Of course I don't advocate no punishment. Without punishment there would be no deterrent for committing those actions in the first place. I'm merely questioning what that punishment has to be.

Cost
Life imprisonment is cheaper than the death penalty. There's no economic reason to do it

Rehabilitation
It's fairly impossible to rehabilitate a dead person. Even the worst, most-hardened criminal has a chance of rehabilitation if alive. Certainly not so if they're dead.
Mistaken Identity
This is a big one. Huge one. If you wrongly identify the criminal, then carry out their death penalty, the best you can do if you find out they're innocent is shuffle your feet nervously and apologise to the families, maybe compensate them. If they're innocent, you can free an innocent person.
Obviously all these things are adverse effects of a corrupt system that could and should very well be fixed. This has less to do with the practical pros and cons of capital punishment and more to do with realizing how convoluted and inane our judiciary system is.
Applying the same reasoning to government would equate to something like getting rid of all authority whatsoever because executive power can be abused. You're throwing the baby out with the bathwater.
For starters, the possibility of rehabilitation on the living and the impossibility of rehabilitation on the dead is not an "adverse effect of a corrupt system", unless you count the lack of necromancy today as a problem. It's a real issue, and as it was not attacked by you I do not need to defend it further.
Mistaken identity is always a problem, regardless of the system. We'd need to have an utterly perfect judiciary system, evidentiary system, everything. It's something that can't be fixed short of that. It is the permanent nature of death that provides a problem in our current system, so at least until Minority Report becomes realised it's a problem that has to be considered when addressing the flaws of capital punishment.
The cost, well, you may have a point there. That's a problem with our current system, and it could easily be fixed within the foreseeable future. However, in the light of everything else, I don't see why it should be fixed.
