When you look at it though, Plankton may be evil, but Mr. Krabs isn't all that nice and good either, he can be a slave-driver at times, and he is heartless and never gives anything to anyobdy (at least in terms of any form of cash.) Go watch Born Again Krabs and you'll see The Flying Dutchman says he is bad cos he is cheap all the time. And watch The Krabby Kronicle and you'll see him reach new lows of ruining some people's lives with fake stories and balck-mailing and all that, like Larry, and putting Plankton out of business.

And also at the end of the episode he counterfeits and makes himself all that cash, which some are saying here that that sends a bad message to kids.

So when you look at it, both of them can be bad, so its like villain versus cheapskate villain competing for a better restaruant business.

In retrospect, Plankton and Mr. Krabs are like Al Capone versus Atila The Hun.
