Why are they immoral? Perhaps because they're criminals, homosexuals, perverted, murderers, theifs, liars, rapists, adulterers, warmongers, drug addicts, self-serving, barbaric and unbound by any constraints of conscience or moral compass. People do that following all religion u say. Well these are common traits ONLY amongst either confirmed or unconfirmed atheists within the ranks of religion. REGARDLESS of what religion claim to follow they lack fear of God. End of story!
