'Wicked' in the Bible

Now the men of Sodom were exceedingly wicked and sinners against Yahweh.

Abraham drew near, and said, "Will you consume the righteous with the wicked?

Be it far from you to do things like that, to kill the righteous with the wicked, so that the righteous should be like the wicked. May that be far from you. Shouldn't the Judge of all the earth do right?"

Er, Judah's firstborn, was wicked in the sight of Yahweh. Yahweh killed him.
