but i have something to say about this, in the episode "kracked krabs" there are lots of more crabs named " the penny pinchers" which mr.krabs would have killed already, this would also apply to krabs nephews,and Betsy krabs. And yes, just because their his family that doesnt mean he wouldn't murder them. He will do everything to make sure that the krusty krab makes alot of money for him to have. And your video link which shows "more evidence" is out of context, theres even a comment that says its out of context, and the comment says "This is taken out of context, in the episode a woman refers to a patty and Mr krabs as crusty and dried up, so Mr krabs eats the dried up and crusty patty saying "so that's what I taste like"". If you have anymore questions you would like to ask me, Ask me.
