because Iroh didn’t die.
every other damn story I’ve seen the pot-smoking wise kung fu master mentor character always dies but not iroh.
Obiwan and yoda die.
dumbledore and Sirius black die. The fucking turtle in kung fu panda dies. There’s a whole trope about it. Uncle Ben dies after giving peter parker wise words.

But not Iroh. oh no.
THE GUY WHO PLAYS IROH DIES AND THEY still DID NOT KILL HIM OFF
THE WORLD IS GOOD AND PURE.
Mako took the curse so that Iroh could live.
