Why are some people so negative and angry?

My guess is probably, among others,

• Injustice;


• Abuse by others (emotional, sexual, physical, verbal, etc.);


• Disappointment and discouragement;


• Failure...

But there's a way out of it, even for people who are so negative and know the end results of their behavior: To come to God in faith and let Him heal them from the inside out.
