Oh boy, are there a lot of different types out there. Maybe you've met someone or worked with someone who seems to be spring loaded to take offense. What do you think of them? How do you think they got that way? A psychologist would say it's a combination of personality type, physiological situation (anxiety level) which could be caused by any number of things including hormone levels, neurotransmitter levels, brain structure and function, etc.). How do you treat them? Do you provoke them on purpose? Do you treat them gently? Do you treat them like everyone else, even though you know they're different?
There are all types, and there is going to be a certain percentage who are prone to violence after continually feeling oppressed, denigrated, unfairly treated, etc. What's more likely to make that less? Fostering an environment of equity, fairness, appreciation, love, acceptance or treating people with increasing hostility of any sort? What makes a society safer: creating a world with more people who have had enough and won't take it any more, or one that people feel there are avenues for their tough lives?
