No sane person can fail to detect an abundant amount of evil in and around him.
Evil in the world of various kinds does constitutes a problem for theism, but it is surmountable.
The real problem arises when a person decides that the amount of evil outweighs the amount of good; or that life is not worth living; or that he would prefer never to have been born.
This attitude is called pessimism, namely, “a : the doctrine that reality is essentially evil; b : the doctrine that evil overbalances happiness in life.”
Interestingly, pessimism would seem to lead to suicide which reduces the number of pessimists in the world and prevents them from reproducing, thus perhaps stopping their children from inheriting a pessimistic temperament. The “problem” fixes itself, really.
