Does doing nothing make me Evil?

Today on average everything went great. I spent the night over at my Girlfriend's house to get ready for college the next day, I made it to college, I told two of my favorite poems in English class, and I was able to get 5 classes registered for next semester. All things considered it's been a pretty good day.

But (you knew I was going to say "but") on the way home I got really tired, too tired to drive, so I pulled over to an In-n-Out parking lot and rested a bit. When I went to leave I drove through another parking lot just outside a shopping center to see what appeared to be a man giving CPR to someone else inbetween a camper and another raggity old truck. Maybe I was seeing things, maybe there wasn't a man, but the point is no matter what it was, I didn't stop to help. I'm sure he saw that I had driven by since my headlights flashed right over them, but in my mind I just couldn't bring myself to actually help, in fact in my mind all I could think about was distrust. Have I begun to distrust the human populace by so much now that I won't even stop to help a dying man? How low does that make me?

I could have at least driven past him and contacted the police officer I had just passed up earlier but by then I had entirely conviced myself that what I saw wasn't real. I didn't just not help, I didn't even try to "get" help. I know even if I did stop to help I wouldn't have a clue what to do, I never took CPR classes, but I could have found an officer who did. Or at least dialed 911 at a payphone.

I don't know, the whole incident has been wearing on my mind for the rest of the way home. I don't know what happened to them, I'll probably never know. If being a good samaritan has ever influced my Karma I would have to say last night completely voids them all out. For all the good karma and nice things I've ever done for people I can't stand to think I may have just left a man to die.
