Someone wanted to make more money and keep it going?
Even if they did have batman kill the joker, if enough money is to be made, he would come back. That is true of all comics.
yeah I was saying they'd make some sort of explanation though, that he didn't really die, or alternate timeline/universe. so thats kind of different than having a dude that no matter how many times you kill he'll just undeniably come back.
I mean if they really really wanted to they could use the lazarus pit, but that would take some pretty convenient story telling as to how and why he got access to it.
Not as such. Joker has swam into the batcave before just for the lolz and that's not even the only known pit in the world. That's like 7 miles underwater to begin with. Like I said before, Joker has plot armor in spades.
the lazurus pit is heavily guarded by assassins. where as the bat cave is guarded by an old (though capable I admit) butler when batman's not home.
At least the god-damned Fortress of Solitude has a security system ffs...
so does the bat cave actually. the joker just somehow got by it. i've actually read that story arc. but you gotta remember somehow superman got his hands on kyrptonian tech if I recall so he probably does have a more advanced security system. (also canonically speaking hes smarter than bruce)
but getting by security measures that surely batman did NOT design to kill, is easier than getting by a bunch of highly trained assassins that won't hesitate to kill ---
