i am sorry as i do not know yr age--just for yr KBC knowledge--WORDWAR I & II r living examples beside many other WARS--science had the best time as whatever science is today is simply a derivative of science already been at that time and never compare science with religious wars first--then whatever wars r depicted in holy books of HINDUS were also scientific as well as for betterment of society--all those books preach the best and tells us how bad can be family and social feuds--our books r not owned by any individual HINDU GOD as each and every GOD is dependent on other GOD--dependency leads u to tolerance as first makes u to leave errogance egoism--our books cannot be followed truely in all terms as none is supreme as told in our books.Yes u can tend to be complete but not fully--my words r not to contradict other teachings but explain some truth--in HINDUISM none is supreme except the EARTH and MOTHER to some extent as both have to bear many loads and their CALM nature make us to survive--once they get violent---then it is over--lalitkumar
