Would a world without religion be a better or worse place?

Personaly, I'm Asatruar, the religion of elders nords gods (Ases), but I don't take it serious, I see this more like a game and a way of life than a really serious thing. I do some rituals and festivities, but always for fun, it's never a constraint. So I think religion is a good thing when it's just an occasionnal hobby, it can be a work, but like a games seller : you do it because you like it, and you don't dedicate your ENTIRE LIFE for it. I also think that religion must be forbidden before a certain age, peoples must choose their own faith.
