Anger or violence is a part of human nature. Though for some, it might have been locked down below but, just like we have in volcanoes, there is a tendency of an eruption some day.
The fact that, we could get angry at some occurrences or happenings in our lives simply means that, we could raise arms against one another or nation against nation some day.
We could only hope to avoid but, it’s just something that happens.
