"'Good' implies altruism, respect for life, and a concern for the dignity of sentient beings..." --- Nope.
"People who are neutral with respect to good and evil have compunctions against killing the innocent but lack the commitment too make sacrifices to protect or help others..." --- Closer.
"'Evil' implies hurting, oppressing, and killing others. Some evil creatures simply have no compassion for others and kill without qualms if doing so is convenient." --- Bingo.
Likewise:
"'Law' implies honor, trustworthiness, obedience to authority..." --- Nope.
"'Chaos' implies freedom, adaptability, and flexibility." --- Perhaps.
"Someone who is neutral with respet to law and chaos has a normal respect for authority and feels neither a compulsion to obey nor a compulsion to rebel." --- Yup.
Therefore, I'd say he's Neutral Evil, though a very good example of how a neutral evil character can still be heroic.
