Alignment changes from vile races will only help, not hinder. Ex: A blood red Gradius paladin kills an evil orc. His alignment is pushed towards good. A neutral Gradius paladin's alignment will not be changed by killing an evil orc. A light blue Gradius paladin's alignment will not be changed by killing an evil orc.

These changes now apply to the following combos:

Gradius paladins vs. vile races
Werewolves vs. vampires
Other paladins vs. deathknights - this was pretty much guaranteed; when was the last time you attacked a royal blue deathknight? But it's been put in for completeness sake.
