...be considered a sin? Some people enjoy saying things they don't believe just to get some attention. Just like they are happy that our troops die in iraq, they sometimes reply to the questions of pregnant mothers like "I hope you have a miscarriage" or "your bf will dump you and you'll be a single mother" stuff like that, just to vent their anger at their failed lives.

In the light of this, do you think its a sin in god's eyes? Any sources available (I googled "Trolling is a sin" but to no avail)
