Hey guys! I've been on Danbooru for quite a while now, and one of the things I've been thinking of is how it lacks is a tag or pool for what I'd call "good versus evil"-themed images.
The concept of good versus evil is quite well known and is present in a large number of topics. Here are some Danbooru-images I'd label as such: post #455210, post #1511400, post #769829, post #792132, post #1346785, post #900353, post #158151, post #1201830, post #1241838, post #589898, post #643036, post #699482, post #955059.
There are, of course, other pools/tags that these images fit in too, but none that deals with this concept. The "To the Death"-pool includes, for example, any fight that's intense enough, regardless of underlying reasons. The "angel and devil"-tag mainly includes girls with angel/devil wings, rarely showing any combat ( or even going the other way ).
However, I'm unsure of whether it should be a pool or a tag. Given how "good vs evil" is a common concept, it probably has the potential to be a tag (like "angel and devil"). Still, at the same time it does have a flair of subjective opinion which makes it more suited as a pool (I guess), despite how some images are clearly depicting this concept. What do you think? :-)
