Definitely thought about it. Think i'd actually be pretty good, too. My obsessive compulsive nature would insure that no mistakes were made and no traces were left.
I'm almost positive i could be an incredibly effective serial killer.
And no one would ever suspect me. I have spent all my life building up an absolutely flawless record of good character. They would NEVER see it coming, nor suspect me.
It's true what they say: It's always the quiet ones....
Though in university i had a 3rd year computer class that required a massive group undertaking. There were 5 of us in the group. It was a computer programming assignment. We all had our parts to program, and one member of the group volunteered to be the person to compile it all together and submit it. Well, he compiled it all together, and then tried to alter the program in a manner that would incorporate the latest and greatest programming techniques that we had briefly brushed on near the end of the course. He failed miserably, screwed up our program, hadn't saved a backup, and instead of calling us to ask us to resubmit, he submitted what he had (which wasn't working) and then literally skipped town. We never saw him again.
We of course flunked the course, and all of us made a vow that if we ever saw that guy again, we would kill him.
