Telling people they shouldn't do obvious bad thing is pointless because those with good ethics wouldn't have done it regardless and the others won't care about

Telling people they shouldn't do obvious bad thing is pointless because those with good ethics wouldn't have done it regardless and the others won't care about your comments. Your consequentialist view is valid but you can not demonstrate without a shadow of a doubt that it's the best and most useful perspective. If you think your way of thinking is so much more superior then start your own startup, be successful, donate to charity and then write a blog post proving us all wrong. The reason I'm investing time into this discussion is because I believe your way of thinking is toxic and very dangerous because you actually believe you're more virtuous for the beliefs that you hold. The most atrocious events in history have been done in the name of good, please remember that or you risk increasing mind share in toxic and evil ideologies.
