Peter Griffin (seasons 8-present)

"'Remember what I always tell you, if I come home in the middle of the day and catch you having sex with someone, I'll kill you both.'"

Peter Griffin is the titular main protagonist of the FOX animated comedy series Family Guy; however, he is not as nice a character as some may imagine in fact throughout the course of the series, Peter has caused much misery for those around himself: often this is due to stupidity but there have been times when Peter has deliberately caused harm or misfortune on others to better himself, which only backfires, leaving Peter the raw end of the deal.

Peter is not alone in this respect as he is shown to have an "evil" brother known as Thaddeus Griffin, suggesting antagonism runs in his family, that explains about his son, Stewie (though in fairness, Peter does have some moments of being a caring individual, though they are rare).

He is voiced by the Family Guy creator Seth MacFarlane.

Why He Sucks

 * 1) Although not exactly villainous or evil, Peter is shown to be a stupid, rude, crude, moronic, short-tempered, stubborn, selfish, reckless, egotistical, and argumentative person who causes misery to a great deal of people around him, rarely feels affectionate towards his children, especially Meg, and even with Lois, he has shown a great deal of disrespect towards, cheating on her on several occasions.
 * 2) Most of his time is spent with his drinking buddies, getting wasted and going wherever he wants, doing whatever they want, and costing thousands of dollars of damage with his drunken or sober tomfoolery. He has been willing to do much more for his friends than he has for his family as well.
 * 3) Another example of his negative aspects is how terrible of a husband he is to his wife, Lois. Peter almost always takes her for granted, despite him being considerably lucky to have her due to the fact that Lois was the daughter of a billionaire, is very attractive and has had the affection of several others around her who are arguably better people than Peter. There have been more than enough instances to show Peter has been cheating on Lois, such as when he admitted on television he knew the names of every pornographic star, even those who had joined an hour before, and has been openly shown to either have attractions for other women and former sexual partners during his marriage with Lois.
 * 4) He is also shown to be an absolutely manipulative, atrocious, and cheating father, demeaning, demoralizing, pranking and downright abusing his family, especially Meg. In fact, Peter actually left Meg behind when she was in mortal danger, saying that he and Lois had decided if they needed to leave a child behind, it would be Meg. Along with this, he openly admitted to everyone that he hated the kids, simply because they didn't do anything or weren't entertaining. However, there have been moments in other episodes where Peter has been there for his children, having good times with them, getting some laughs, and even taking them to fun amusement parks of parties.

Redeeming Qualities

 * 1) In the earlier seasons of Family Guy, Peter was a more likable character.

Trivia

 * He is very similar to Eric Cartman from South Park as they are both selfish, abusive, racist, misogynistic sociopaths who would kill anyone just for their own personal gain however unlike Cartman what Peter does lacks comedy.
