The problem with Religion

"Religion is a major part of human culture, to determine humans place in life or where we stand. However it is plagued by its own followers as those who claim to be religious always ironically go against there own religion, There is no such thing as a true christian or Islamic as they only follow certain values of it." Dr.Philo

Christians have been waging war forever and yet in the bible it says taking anothers life is a sin, How is this following christianity if you use it as just a excuse to be manipulated by your own inner greed?

Islamics claim there religion is a religion of peace yet they make signs saying kill all those who insult islam?

However in the Qisas it says

"O you who believe, equivalence is the law decreed for you when dealing with murder - the free for the free, the slave for the slave, the female for the female. If one is pardoned by the victim's kin, an appreciative response is in order, and an equitable compensation shall be paid. This is an alleviation from your Lord and mercy. Anyone who transgresses beyond this incurs a painful retribution"

How is this peaceful? It is as ironic as a christian not following the bible.

Having such a profound belief is not wrong, no it shows how you value life and how you go about it with its own moral rules and the belief that we humans aren't just creatures who only kill each other to satisfy our own.

But if you choose to believe. Make sure you follow its own rules correctly and not just change it around so you can get the better.
