Why do men perceive the worst in women and generalize?

I have noticed that it's very common for Indian men to justify cheating saying that woman are probably doing the same. Which is just not true. Do you think men and woman are given different concessions to cheating?

Also when a one woman makes a mistake, then all 'females' are gold diggers/hoes but when a man makes a mistake, it's because of his 'manness' and "not all men'.
