Sense of justice is good.

See if you can use concept of justice in one way.

Tell yourself that justice was already served, he is in his 30s, should be great time in ones life. Ha has no education and no career, lives with his parents and mooches off people (either family or short term girlfriends -no one would stick around long enough let alone ever marry him or have a family with him). He spends free time intoxicated or on social media posting on forums and causing drama. That’s not how successful 30 something live. It’s my daughters generation, I know many 30 something year old women and men and it’s not how they live, his life is messed up compare to others.

So that’s justice. If justice is important for you in this case.
