Greetings and peace be with you Studentofdeed;
I know Allah loves him.
but how can I remove these feelings of anger
You give really good advice to others on this forum, and I believe deep down you have all the answers you need.
You will never look into the eyes of anyone who does not matter to Allah, and you say that you know Allah loves him. Reflect on the 99 names of Allah, and you will come to understand what you must do. Always search for the good that exists in all people, they are a part of Allah's wonderful creation, strive to be an encouragement and an inspiration to those you meet.
May you be blessed with the wisdom and the kindness to do the will of Allah.
Eric
