I still don't understand why Turtlekid thinks that he can be an evil jerk if no one's looking. And I also don't get why he doesn't understand the principle of the golden rule. I mean, do you want to be robbed? Do you want to be killed? No? Then why would you do it to someone else?
The "moral standard" is perfectly maintained by the golden rule.
If he's a drain on society, then he needs to die for the greater good.
Dude, you are making this $#*@ up. No one else thinks that way. You either have such a skewed understanding of society as to be completely unrecognizable, or you are just trying to create situations that you think help your argument.
I can see that your mind is twisted though by your repeated mention of "consequences". Why do you only want to do the right thing if it gets you into heaven? Why not do the right thing simply because it is the right thing to do? Someone truly "moral" wouldn't be doing things simply to be rewarded later. That's completely missing the point and I think God would be very disappointed in you.
To recap: Consequences don't make something right or wrong! They are simply a byproduct of your actions. Thus I ask you again, would it be wrong to kill you if I felt like it and I knew no one would know or care? Of course. Even if you have the mentality of a totally backwards and sickening troll. I don't want to be killed and think it would be wrong to be killed, so logically I must conclude that other people don't want to be killed either.
