God is not "mean". God gives grace and is merciful, but He can also turn people over to a reprobate mind.
Romans 1:24-32 (KJV)
24: Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
25: Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
26: For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
27: And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
28: And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
29: Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30: Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31: Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32: Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
