Most blanket statements are usually matters of opinion.
It is true that religions including Christianity are evil, however
they can also be a source for good.
As with all things there seems to be a distribution of good and evil when it comes to the human experience and religion is no different imo.
I personally think that religion serves as a way to unify people as well as cause wars and tear us apart.
The building of hospitals and schools are good.
The wars and destruction are bad.
The charity good and the extortion bad.
There are religious scientist that make great contributions to mankind as well as atheist scientist that do so as well.
A interesting question is what would humanity be like today if not for religion?
Would we have ever made it out of the dark ages? Would knowledge have been preserved?
Every great civilization seems to have hit upon some version of religion. Some of the greatest architectural achievements where religious shrines. Religous evil and good are part of our story and I can not think it is all evil.
