Rico didn't kill Visari, Guerilla did.
They killed off one of the only interesting characters in the entire series, and even used Rico's rage as a lazy way to do it. I don't see what's with all the Rico hate - they could've replaced him with anyone else in the squad to kill Visari and it'd barely make any difference. Sure he cusses alot, but he's definitely a much more believable character compared to Garza, who kinda ruined what was supposed to be a gritty war-like setting with all the lame jokes in his dialogue. At least Rico shows some aggression and feeling towards the Helghast.....Garza looks like he just came along because he was bored er somethin.
The only interesting parts of Killzone's story and background is the stuff that isn't even included in the game. What they give us instead is a half-assed ending. If they really wanted Visari dead, they could've found a better way to do it. Still though, they could've done lots of interesting things with a captured Visari instead.
If GG is gonna continue putting the main story events on the internet and save the lame parts for the game, then I can't say I'm excited about what KZ3's plot will be =\
