When people took justice in their own hands they don't feel good that they did it...Some do for a few days;..But almost everyone feels bad that they took justice in their own hands;.. You probably had a situation like that aswell on forums or in your family/friendclub...Someone fucks you up...You get mad....And you say some horrible things...Next day you wake up and think..'why did I said that;..I feel so stupid'...
Just try to use energy of your anger to help people like other victims...
