Humanity is capable of a great many things, whether they are great or terrible things. It seems today that people have forgotten that we are all really the same, and should all have the common goal of bettering ourselves and enhancing our day to day lives. But instead they are so concerned about getting what they want whether it be power, legislation, or political gains they will stop at nothing even if it is at the expense of their fellow countrymen. There are radicals on both sides that make completely rash decisions and without reason. Humanity should be at peace with itself, because the more fighting that ensues the more that we hurt ourselves, we all should be united under one power and one flag. Yes some wars are needed because some individuals and groups such as terrorists or other violent extremists, these people benefit no one and really just manipulate their follower's beliefs.
