No it isn't (I'll assume that comment was aimed at me, because of my views on it).
I used to be very anti death penalty. Then I got really into True Crime and the Nazi's. And reading and watching all that stuff has led me to questioning that stance. Because for as much as I'm mostly liberal in my beliefs, I also accept that there are some really bad people the world.
Crista Pike was dealt a really shitty hand in life. But none of that excuses what she did. I'd have had a lot of sympathy for her BEFORE she did what she did. But lots of people are dealt shitty hands and don't murder a young girl (she was 19). And do so in an utterly sadistic manner either. Collen Smellen must have died terrified, and in severe pain.
I'd say there was a very good chance Pike would have done it again, had she not been caught, and kept doing it until she was.
My sympathy lies with Collen Slemmer and her family. If that makes me an internet baddie, then so be it.
