We dont need force and agreesions to move or motivate people to do good deeds. Yes, just believe that most of the times, encouragements and gentle persuasions would do a better job.
However, there are people who are so set and determined to turn minor obstacles into major dramas. No matter what others tried to persuade them to be change their negative attitude, they just wont listen.
These group of people are destructive. Good samaritans should fight them to ensure we have postive progress.
