There are six things which the LORD hates, yes, seven which are an abomination to Him: haughty eyes, a lying tongue, and hands that shed innocent blood, a heart that devises wicked plans, feet that run rapidly to evil, a false witness who utters lies, and one who spreads strife among brothers. Proverbs 6:16-19
Most of the time when we consider the things that might really displease God we think of murder, stealing, and stuff like that. While this passage from Proverbs does state that shedding innocent blood is something God hates, He also includes arrogance (haughty eyes), lying, thinking up mean or wicked plans, delighting in watching/knowing about something evil (or perhaps something we might just consider entertaining drama?), and being divisive.
