The Spectre is the Spirit of Vengeance, sent by God/the Presence. He exacts revenge on evildoers by giving them karmic deaths. Not everyone likes that - Batman doesn't, but hey, he doesn't like anyone. That Hal Jordan served as its human host for a while didn't help either. When Spectre showed up in Blue Beetle's series, good Catholic boy Jaime had serious faith problems because of Spectre's ruthlessness. That's a recurring theme, but not always played out so well - Tales of the Unexpected v2 could have been so much better.

Spectre's generally a good guy, but he has always been a loose cannon (or, with his powers, a loose A-Bomb). For a time when he was without a host, he became enthralled by Eclipso (who was retconned as his "sibling", God's Wrath) and killed a lot of magic users and later even entire nations. He's not really happy he's bound to Crispus Allen now.
