Everything we know about The Red Guy comes from a single source, his worst enemy, the George Volcano. This is why he is so evil because an enemy would never speak the truth of the other. No one stopped to think that Satan also has feelings, and that perhaps he's hurting his own life for things like sex and with a simple condom. So, to understand Satan's feelings we must know his motivations, his hopes and desires and knowing basically his gayness and his sad existence.
