The world is encapsulated with so many religion embedded with different doctrines, teaching and belief which have affected our sense of reasoning in different ways. Religion has raised serious concern to mankind especially in terms of sociopolitical and economic coexistence. The major cause of insecurity in most part of the world today is the problem of economic and religion supremacy where everyone seen to uphold their religion with virtue and in a high esteem and even considered it to be the only true region and the only way to salvation and internity thereby condemning or seeing other religion as fake. So therefore, considering the problem associated with religion differences in world today, I think the world would have be a better place without religion.
According to Karl Marx, religion is the opium of the masses, it gives people a sense of believe and belonging so if you remove it from the society, people might not see any moral rights to define their characters. Most religions teaches about peace and I believe that if it's not for this reason there will be more chaos in the world because there might be no conscience or guilt to refrain people from doing evil. So my point is that religion to a large extent helps to subdue the evil in human beings, atleast the two most popular religions upholds peace and love.
A lot of evil and criminalities are happening in the world today even with many religions that admonishes peace and love, so how do you imagine that the world will be without them. I think that lawlessness and wickedness will be greater than good because humans by nature wants to conquer and rule their fellow humans, religion puts these characters in check by teaching humility.
