Why did God create humans and why does he let us suffer?

because suffering builds character especially conscious self induced suffering, the only place on earth that qualifies as a paradise where all needs are met would be in a zoo, and in captivity we see animals who have never attacked a human in the wild like whales and dolphins, using deception in order to kill just one human, purely out of spite, while others like great whites just die outright.

this is what paradise is, a cage where no one has any room to grow, they become stagnated and disillusioned. .
