One of the worst things Brian does is that he tries to seduce Lois, even though she's already married, and to his best friend nonetheless, the man who saved him from certain death and pays for everything he buys, and never pays him back. I'm not done with the hitting on though. And it's not just Lois, remember when he ran away with Bonnie? He deserved to be shot in the leg at the end. Hell, Joe should have put him in a coma. I'm just not a savage to actually finish the job...yet. Overall, Brian is the worst when he hits on women for their bodies, and it's even worse whenever they're married

Not to mention attempting to rape her.

Why is that a bad thing. Religion is a virus on this planet. You do realize that Christians were burning books just before Brain said that, which is way worse. Not to mention do you remember how Christians were treating Brian after he said he was an atheist. That is why I hate religion. I have been treated the same way by religious people, and I have been nothing but nice to everyone. - westofohio
