3. Julius (Saints Row)
Julius and Troy recruits you in the beginning of the game after they save from the Vice Kings gang. They helped hone you into becoming a big gang figure. However, Troy turns out to be an undercover cop. The good thing is that he showed reluctance in arresting Julius and even warned the former to cool things down so he wouldn't arrest his friends.
Julius decided to skip the pleasantries and decided to bomb the yacht you and Gat were on to stop your rise to the top. He may have his reasons as he sensed that the player was becoming more power hungy, but betreyal is still betreyal.
