We should make him realize that what did he did and it can spoil his future.Making him understand is better than scolding.Keep an eye on him that where is he going,what his he doing and which kind of friends does he have.Make him do chores and other good things if he has no work to do.If he's an adult  we should explain him that his personality is becoming more unpopular ,He is representing his country everywhere. Dont encourage him to do bad things .Keep urself alert and serious
yes , u answered pretty well
thx urs is good too

see what we should see why the person is doing wrong things and then tell him that it is wrong .we should take a look at both sides of the situation , why the person is doing such things and if no specific reason then we should tell him the consequences of doing such things may lead to and don't forget to be patient and calm because wanting to do things in a hurry does not gives a good solution.

I hope my answer helps u :)
