Come on dear.
Stop being judge and jury, passing judgments about others without you knowing the truth.
What makes you think that you are hundred percent correct? Even if you think that you have the sixth, seventh or eighth sense, who wants your opinion anyway? Especially about others' flaws?
Don't you think it is terribly unjust to label someone according to your preference and convenience?
The tables might be turned one day. Those whom you hurt today, might be the one who will help you one day. And all those hurtful comments and remarks will be one day just describing you or your kids.
Keep your opinion to yourself.
Be fair in giving advice.
People have feelings.
Even animals too.
