This character plays the role of an antivillain.

An antivillain is the opposite of an antihero — a character with heroic goals, personality traits, and/or virtues who is ultimately the villain. Their desired ends are mostly good, but their means of getting there range from evil to undesirable. Alternatively, their goals may be selfish or have long-term consequences they don't care about, but they're good people who might even team up with the hero if their goals don't conflict.
