Depending on what you hate and how. There is a thing called righteous wrath. When you hate sin so much you are wont to suffer it and will talk to anyone, lead by example, anything so that the thing you hate is out of your life (as for the sin itself, we are all fallen human so yes we would still sin despite our best, but it will be kept to very minimum and for every sin we committed we will repent and atone).
Pray for them to be spared hell and pray that any suicidals you will come across in your life, you will have the ability to save them and save them you will. This may be very heretical thought, but I think of people committing suicide, murdered either by daemons and/or human forcing the circumstance. Daemons trick us into believing that everything will be better (for friends, family, etc.) if we spit on Gods greatest gift, life; when all it will do is cause trauma, sadness, another hotbed to beget sins, etc.
Like I said in the earlier post, I have been there and suffered as we all do. Daemons keep telling me even now that I should off myself when I was 12 just to spite everything around me and make the tormentors pay. In reality, the little sociopaths would not give a winnie the pooh and the only devastated party would be my friends and family. I hanged on and so many years later the retribution visited upon them and that place was of an epic proportions. Long story short, a prestigious Christian school gone horribly wrong back then, corruption, drugs, 'extreme bullying' (stabbing, assault and battery, theft, rape, etc.) and everything was swept under the radar and any students calling out on it would get what I got. Years later, shit is exposed and the 'purge' of staffs and boards and the fallout on the perpetrators that followed was a retribution returned seventy-seven fold and so much more.
Yes, sometimes it seem like the bad guys do not just get just desserts, but believe me on this. They living a life that has to be paranoid of anyone because everyone around them is aiming for their chairs, money, etc. It is a punishment in its own right, all the money will not save him. The sociopath that I know is working for UN that is leading an extreme debauchery lifestyle? When all the misdeeds are exposed it will come crushing down like a hammer from heaven on him unless he repent (but afaik, pride and worldly matters which he is obsessed with keeps him from that). I pity his lifestyle and dread the day of reckoning should he not repent, he would become a figurative corpse for the other vultures of a company he keep to feed upon.
