Two people ate a fruit that He had forbidden to them and not only did He put them on death row with hard labor (the man hard agricultural labor, the woman in hard labor when bearing children); He actually kills them. And also all their descendents, generation after generation.
Actually, the Satan embodied as a snake tells them that G^d only told them not to eat from that one tree because it would make them equal to G^d. And G^d doesn’t tolerate equals. We know that Angels may entice but never lie. G^d needs all the glory? Is He a bully?
And while claiming He’s omnipotent and omniscient and loves us, He stands by idly for millennia when millions are killed and murdered.
Meanwhile, He passes as the righteous Judge of the whole world.
How does He get away with all this?
Good question. No public relations agency could work with such a Client.

Atheists deny Him so they have no bone to pick with Him.
Some people think that they are Atheists but they are angry with Him so they are not. And they don’t let Him get away with anything.
I can’t speak for everyone. But as a religious Jew, I do have answers.
When G^d knocks off people, He doesn’t end their lives. He only passes them on, to outside the Garden of Eden, an Afterlife or a re-incarnation.
Nothing in His creation has permanency like He has. Everything withers. Aging parents who don’t die, take away precious care time from raising children. So, to help parents, He lets their parents die in time. With the promise that eventually, Death will be slaughtered. And of course, also aging. So then, the conflict is resolved and the dead can be revived.
