Yes I do agree that Pain makes people change. It makes them trust less, overthink more, and shut people out so before you hurt others, think about how much it will affect them because they may be able to forgive you, but not all of them will be able to forget what you did. We are only a human who hurt, who felt pain and always change our mind. Thats why we need to be wise and if someone will trust us we need to takes care of it.
I agree. Indeed, pain may be healed but it also changes the person's perception as well.
