He killed a tree because it didn't produce fruit as if the tree was deliberately holding out on him. Like you're literally God who literally created all living organisms, surely you understand how trees work and how they will turn off fruit production if conditions aren't right (namely if they don't have enough nutrients for it), and that it's an automatic response which the tree has no conscious control over because you didn't even design them to have a nervous system.

I mean, also the "I love you unconditionally, on the condition that you worship me otherwise I will personally throw you in hell" thing.
