If what you allege your friend is correct, then he is indeed guilty, and he will be accountable for such grievous sins unless he repents and changes.

 

As for his good deeds, you don’t need to condemn them; Allah will judge them according to his intentions. So, let us leave the judgment to Allah.

 

We are not allowed to put out a person from Islam because of his or her sins no matter how ugly they are.

 

The belief of ahl al-sunnah is that a person will only go out of the fold of Islam if he were to denounce Islam or to deny any of the fundamentals beliefs or practices.

 

You should not abandon your friend even if he is guilty of such heinous sins as you allege. You should like at him like a person who is drowning. Would you save him if he is drowning? Of course, you would; spiritual drowning is worse, for it would deprive him of eternal salvation; so, do your best to advise him and persuade him to change. And never forget to pray to Allah for guiding him and all of us to the straight path.

 

Almighty Allah knows best.
