Everything has two sides in universe, one is good, one is bad. A person is friends with someone and enemy of someone else, a thing might have good effect on you but might harm somebody, even the laws made for our benefits are misused by some people, all the objects of this universe has two sides just like a coin. We should always accept that everything good comes with some bad too. We should always be prepared for that too, there is nothing in this universe that is all good or all bad. Even if we breathe we are taking the oxygen and giving carbon dioxide to the environment. It is similar as we are sitting in an a/c car, it’s cool inside but leaving double as heat outside. We can’t change it but can only accept it, “there is an evil in every god and god in every evil”.
