The good book says bad company spoils good morals - Fact.
Having said that this is my take:-
It is apparent that there is conflict between your environment and your inner core beliefs. Nonetheless, man cannot live in isolation.
Way forward:-
1. Explore (within your circle of influence) contacts with people or areas that you belief will share your aspirations.
2. Maintain "essential" (bro and relas are permanent) contact with this group, who knows you may be the "angel Gabriel" they are waiting for albeit unknowingly.
3. I agree kuishi kwingi ni kuona mengi but the fallacy is many see the mingi and are rarely effected positively by them, u can get an irresponsible white-haired human being. Be the wise man i think you are.
