God created Lucifer to be his right hand kinda guy.
God lets us do things because he wants us to make our own choices. This is why we can talk and think unlike dogs and cats.
God does not kill directly. And plus since he is perfect anything he does isn't a sin.
Base on the bible and the story of adam and eve this is not true god did not want us to make our own decisions, adam and eve were created without the knowledge of good and evil which is the same as the ability to reason and thus the ability to sin, he did not want them to take from then tree they did and thus took that right which was not given to them by god, also just to defend women eve did not commit a sin in that story, sin requires knowledge of evil and knowing u are doing something wrong b4 eating the tree she did not have the knowledge of evil and thus did not sin thats a christian spin on the story
and the old testament defiantly supports wethepeople the god of the old testament is whinny and bitchy and makes mistakes
