At the end of the day we're only human.
No one deserves to get bullied or harassed, we all have feelings, and we all react to things differently.
That doesn't mean we're a bad person though.
We all make mistakes, we all hurt, but at the end of the day we're all only human, no one is a robot.
So the next time you say something or do something to someone, think about why they're reacting or feeling the way they are, ask them, don't just assume things.
