To answer the first inquiry, yes they can, Kenpachi is good example but an even better would be his predecessor, Retsu Unohana. Those examples aside though, keep in mind that sadomasochism exists, a character may want to help innocents and not want to hurt those who do not deserve it but still be biologically-hard-wired to literally get off on pain. This isn't common among heroes who are also pure of heart but it can occur.

And on the second matter no. Keep in mind Angels are basically 'made of good' similar to how King Piccolo was made of evil manifested. And there are numerous examples of evil Angels to say nothing of the just less than purely good ones. King Piccolo reincarnates himself as Piccolo Jr. The symbolism of this character, initially born of the exact same physical manifestation of evil, is that it isn't birth or biology that makes one evil but the identity one creates for themselves.
