Why do Cancers offend villains?

Cancer: Got too many benefits.

Most Cancers are very low-key, and they try their best to do good things to others, but his behavior will make people jealous, thinking that he has to be a good person and do good deeds at the same time, and get promoted and make a fortune along the way, which makes people feel that he is a god. There are no such lucky people out there, so I think Cancers are very scheming.
