I Got Called For Jury Duty

I have had to go for Jury Duty the last two days. It was a trial for an alcohol related offense which I have done before but this time we had to decide the punishment. Previously the judge did it. Now that it is over, it is really starting to bug me that we could have really ruined this guys life by costing him his job and so much money. I know he committed the offense so needs to pay the price but still who am I to have that much control over someone. I don't deserve to cast punishment on someone. It really did not hit me before or during the trial or even right after it finished but on the way home it sunk in. I get it he could have really hurt someone and needs to be taught a lesson so he doesn't do it again but I have done something somewhat similar before but did not get caught. Granted mine wasn't as severe but still. I guess it really bugs me because I was part of the sentencing phase and to think I could have really hurt someone just tears me up.
