>She keeps them in check, and wil fix any who step out of line.
Eating humans who wander inside Gensokyo or get lost is not out of the line for her.
Besides she doesn't actively keep anything in check
If you knew her character, you would knew that she only intervenes at the last minute, when it is a matter of 'becoming annoying to her'
>They gather there, but continue to fuck up the rest of the world.
Not really, besides Yukari gaping in some people occasionally, they have little influence over the outside world
Many who enter Gensokyo can't even leave anymore, so that really limits their activities
>It's related when it comes to human superiority over youkai who eat them.
Humans in Gensokyo are pathetic, they don't deserve to be called superior aside from a select few who are exceptions to the rule
Though it's not like humans in the outside world are any better
>Until all human eating youkai are purged, humans should continue to kill them.
Humans living inside Gensokyo have no reason to hunt Youkai as they are content and safe
Only those who wander in from outside are in any danger
