I don't like being the bad guy. Never have. I was lucky to get through an hour of redside without feeling like I needed to log off and take a shower. That's why I had 50s of every hero AT (back before GR, and yes, that includes PB/WS) before I got my first – and only, really, the dom was mostly blueside from about 35 on – redside 50.
Then came the Freedom revamp to redside's starting experience, and Lt. Harris' arc disgusted me so much that the prospect of taking any future villains I created through it made me swear off making any more, and I planned to take my other villains to full heroes (but most of them languished in the single-digit levels while I constantly rolled new heroes). I left my original red 50 as a rogue so I could keep the base I put effort into building, but that was about it. With Breakout, Kalinda, and Burke available again, I've rerolled the 2 characters whose stories involved Arachnos breaking them out of the Zig as villains, but one of those I did DFB and radios till 20, then tips to switch to hero, and the other I haven't done very much with.
I was a badger back in the day, so I periodically took my main redside to get the badges, but Lord, even the vigilante tips were a slog. Redside is one of the big hurdles for me to getting back into serious badging.
tl;dr: Not a fan of playing villains.
