Do you kill derrick or Francis in grand theft auto 4?

It is not going to change the ending any if that is what you're asking, or how many guys you fight in the funeral mission. Personally though I shot Derrick; given the choice between a corrupt police commissioner, and someone who betrayed his friend, sorry, I let the cop live. If Francis did not become Police Commissioner someone else would have anyway; Francis lives, HE is the corrupt comissioner. Francis dies, someone else is the crooked cop, since you're gonna get a dirty cop on the comissioner seat no matter what, the logical choice was the drug addict traitor. I know its just a video game, but the way Derrick betrayed that guy just really pissed me off; given the choice I couldn't wait to snipe him. Also, every time I beat the game I always let Kate die just so what's his face prison rapist who helped his brother betray that guy would suffer. Kate never put out for Niko anyway! Bros before Hos man, and Roman IS Niko's cousin!!!!
