Video games are not even trying to hide the fact that female characters are oversexualized, but male characters (though most have clothes that cover up most of the body) are also given this treatment from voices, to appearances, to personalities. Sex sells; simply be aware of this fact and don't let it bother you.
No every action / thing has both a good "side" and evil "side"
People choose by morals, and these morals are fragile ideals set upon throughout development. What they cause is unneeded subjective views; it creates the illusion of good and evil. However, there are two sides of every story and if we truly believe in equality, both sides are completely entitled to feel however they choose. There should be no ban on what one wants or does not want to act on.
