If it is (which i am guessing) it is certainly not limited to christianity.
I don't know how many times I've watched TV newscasts where they've caught a rapist, wife beater, child beater, arsonist, thief, swindler or murderer and neighbours, friends and family members all say, "But he was such a nice guy!"
Nice is subjective and relative. It is empty and hollow in meaning by today's standards. It may have been nice for Beaver's day. Ahhh, those were the days...
