I have a question for you. If God tomorrow would reveal himself, would atheists actually believe? Would they still believe in him? Will atheists come up with all sorts of theories to explain what happened? Was it a hallucination, or some magic trick played by someone, or some other medical-scientific reasoning behind it?
I am an agnostic.
If there were real evidences that god or god's exist, then yes, I would believe, because I would know then.
BUT, believing in or knowing any deity, don't mean I would worship a deity.
If a deity threaten me with eternal hell, if I don't worship him or her or them, then that deity is not worthy of being worshipped. I find a god that need to threaten people into worshipping him, is an evil god.
If a god commands me to kill someone, like sacrificing a child or young virgin, I would view him to be an evil god, and wouldn't worship him.
If a god to persecute, torture and kill people for him, because other people worship other gods or are atheists, then I wouldn't worship him.
If I had a child who was born with disability or with terminal disease, and this god was responsible, I would not worship him.
