You should assume you are wrong. You should question everything. You should not allow anything to paint your picture. You must doubt your indoctrination into our species it may be plagued with  misconceptions errors in judgment and execution of sinful activities. If you are  surrounded by monsters teaching you how to be a monster would you realize you are a monster? Dont you think it would have been wise to question that upbringing? How can you assume how things are done are best? Best for you?  Best for everyone?  Not just a compitualtion to what we can achieve over millenia but a millenia changing things now.  We can evolve from barbaric animals killing for survival to gentle beings using kindest to ensure luxury to every single being.  If we question things we would realize world peace fails to exist because no peaceful beings exist.  If you were capable of thinking you might ask yourself how come you arent one already.  Well you'll know when good people exist peaceful beings have no need to divide and ensue a war against humanity.  Mothers fathers daughters and sons present would will their world peace by simply existing.  When it is your reality then peaceful you are and those around you too.  Until then you have some reflections to do. So stop being an ass and think.
