It's actually simple with trap. Just catch SIGINT with a function and call a function to kill the tree:
https://www.linuxquestions.org/questions/blog/konsolebox-210384/bash-functions-to-list-and-kill-or-send-signals-to-process-trees-34624/ Note killtree3. And that could be merged as one single function per your own preference. And do killtree3 "$BASHPID".
