Hanks chances are he'll be fine from the virus in a couple weeks, IF he really has it. Regardless, his day is coming, and when it does he won't be so smug and there won't be any smiling. Who knows, he may panic and call out for God's forgiveness, will it help? That's not our call and I won't even speculate.
One thing for sure, no one, no one can be this evil, laugh in everyone's faces about it and not have it come back to bite them in the ass.
There is a higher power, call it God, Karma or what you will. It's a force of nature, what you put forth, be it good or bad, love or hatred, it will come back to you in multitudes, it's just how the universe works.
“Vengeance is Mine, I will repay,” says the Lord
