Just found out a "Friend" I work with is a sex offender, 2nd Conviction for extreme child molestation Options

[DEATH]

I'm so messed up in the head right now. I feel like killing this man myself and I know nothing of the child other than she was two years old and this is his second conviction. A little background:
I work at a machine/fabrication shop where I'm the head of the engineering department. That means I and the people under me design equipment and parts for equipment that performs a specific function. All of which means I'm out on the shop floor very often, making sure the parts and assemblies I design work properly before they go into mass production. One of the guys I worked pretty closely with in our weld room over the last 8 years or so was on parole for some felony or another - heck most of these guys are. It's just the sort trade that employs alot of ex-cons [I'd say there are more ex-cons than not in the male population out here in the shop]. Now granted, I didn't hang with the guy outside of work, I never had beers with him or any of that. The most I ever saw outside of work was once when he drove his car into a ditch I helped him out, drove him to work. But he seemed like this really nice old man who, yeah maybe fcuked up bad when he was younger and now was just living the rest of his life the best he could. He had several embarresing visits from his Parole Officer up here - he took them in stride, didn't get upset or overly embarresed. He seemed repentative and content to live out his last few years peacefully.
This morning I find out he won't be coming back to work anymore because he was caught sexually molesting a 2yo little girl. Nevermind the question how did he get a little girl like that alone - I have no idea of the details. Sounds to me like some parents need to be going to jail too but that's another question and I have no way of judging that situation [It's just I'm a parent and I know noone is ever allowed time like that around my children with out my knowledge and supervision]. I also found out that that was the felony he was previously convicted of and had served his time for [And I hope those of you who don't support the death penalty for sex crimes are proud of yourselves - I'm sure this little girl would thank you for your kindness if she could. Sarcasm, obviously. If we had executed him the first time this happened another little girl wouldn't have had her life ruined by this horrible act.].
As I said - It's got me messed up. I'm usually a great judge of character but I never saw this coming. I think that if I had found this out before the police did it would be me in jail for murder and him 6 feet under ATM. And I don't feel in the least bit remorseful about that.
These fcuking bastards should all be killed to protect the world's children from them. That's my opinion.
Please discuss this. Please do so maturely. Please respect other's opinions.
Mod's - I'm sorry in advance if this must be closed - I just don't know any other group this diverse that I can get other opinions from that will be different from my own.

thats the thing IF it did prevent crimes then fine do it. BUT IT DOES NOT!!!

I'm trying really hard not to respond the way I want to to all of your other posts, to respect your right to an opinion and so I will only respond to this one thing above:
The Death Penalty would have prevented this most recent act had it been given as his original punishment the first time he committed this crime years ago. Therefore, your theory here is incorrect.
What I think you mean to say is that a known death penalty for sex offenders will not act as a pre-crime deterrant. OK - maybe in some cases you are correct, maybe most of them, but to say it will never deter any of them of them from committing their crimes is rediculous. I can gaurantee you there are people out there who do not commit such crimes because they fear the retribution the state has already layed out for them. You can't make such blanket statements: their almost always false. There are always exceptions to every rule and in this case those exceptions have the result of a few more innocents staying innocent and free from this type of harm.
Good enough and a step in the right direction IMO.
Furthermore: if you, like I, had a loved one who was the victim of such a horrible crime you would change your mind in a heartbeat. It's easy to be moral and selfrighteous from yours, the easy side of the fence.
