Eh, looking through the comments (and its so nice to see that folks really giving some good thought to their comments on such a hot button topic), there’s not much I can add.
I fall into the “humans will find excuses” camp. I also think that religion isn’t a bad thing, per se. Even organized religion doesn’t have to be destructive at its extreme. But it’s also inevitable that the section of humanity that craves power and control is going to use whatever avenue for such that they find.
Since all religions are susceptible to zealotry, I don’t think we’ll ever be free of religious zealots, which means there’s always going to be people insisting that other people follow their religion’s rules, or else.
Now, that isn’t exclusive to religion, but it’s the obvious example of that kind of thinking. You can look at pretty much any bloc that’s belief based and find zealots. Politics, whoooo boy! Veganism. Even fandoms of cartoons have zealotry in a way, though it tends to be a much less invasive kind, akin to music genre fanatics; it’s more gatekeeping than proselytizing. But you do run into the kind of obsessive fandom where if you don’t like it, you suck; and you have to watch/listen/read.
Now, it may seem strange to connect religious zealotry to fandoms, but it’s the same underlying way of thinking. People are just prone to wanting to control other people, and will use any excuse to do so.
That proclivity is present even in people that think they don’t think that way, and actively try to weed it out of themselves. Ever catch yourself thinking "the whole world would be better if they all insert personal belief here? That’s the underlying kind of thinking that can snowball into the bigger kind of problem. Doesn’t even matter if it’s true on a factual level, it’s the way it’s thought about and approached that’s the key. If anything, a belief being highly factual and demonstrably true makes it more likely to turn into zealotry.
So, better without religion? Eh, nah, not imo. Just different in detail.
