It is fascinating that the atheists point to the times Christians or those who claimed to be did wrong to others, but it never dawns on them that the real conclusion here is that sinful man is overall predisposed to pursuing evil which unchecked leads to these types of slaughters of millions of innocents. Not recognizing this historical repeated pattern in humanity, atheists have no restraint that would prevent them from pursuing those very paths that lead to such outcomes. Christianity however is specifically concerned with stopping mankind from choosing paths that lead to slaughtering millions at a time. Granted, the Christians themselves are imperfect and can still misapply truth in scripture to justify slaughtering people who disagree, but the counts of total number slaughtered are typically orders of magnitude lower by comparison. In this way Christianity is a restrainer of unbound evil
