I always wanted to start a poll, except I don't know if this is the right section. If this is the wrong section, you have the authority to move this pole.
Anyways, When you think about it, these two are very terrible characters. here are the reasons why:
Eugene Krabs: He is the owner of an eating establishment called "The Krusty Krab", and he is a freakin' cheapskate. He never pays his employees, he (almost) never gives them a day off or a vacation, and he would even go so far as to sell one of his employees for pocket change. He wouldn't kill people for money, but he would actually tear off someone's limb for a penny that's lying on the ground. If you think he wouldn't go far, You ain't seen nothing yet. One time he actually counterfeited just to gain some money back.
Flintheart Glomgold: (According to Wikipedia) He is portrayed as an ambitious, ruthless, and manipulative businessman who shares many of the same qualities as Scrooge - the drive for massive wealth, and the cunning and creativity to obtain the same - but he lacks any of Scrooge's tendencies towards generosity and compassion. He has no issues breaking the law, cheating and using other unfair tactics in order to fulfill his goal of becoming the world's richest duck, distinguishing him from Scrooge McDuck.
