So, this post has me concerned about you. One of the worse impacts of evil people like these in our life, right after the fact that they work hard to destroy us, is that they inspire negative thoughts and actions that destroy us from inside. Do not let such strong feelings of seeing someone else suffer take root inside you. It will destroy you, your emotional and mental state and your releationships. This is a long war, and each of us are in it. Focus on managing your emotions and mental health.
