If religion teach, fraternity, equality, compassion, love, peace, religion is good.
But if religion bring to fanaticism, fundamentalism, religious wars, killing in name of god, religion is very bad.
So, it depends of the right use or wrong use, of it.
For me religions must bring people to comprehension, understanding, not to fighting, not to wars, and to dull discussions and arguing.
And religions must not be used by politicians as instrument of control and for politic purposes.
Respect to each other must be the aim when we talk about religion.
There are very good religious people and people that misuse religion. There are also very good atheist citizens.
