Package removal does not stop running bots

[sebix]

Removing intelmq (3.4.1~alpha1-1) ...
userdel: user intelmq is currently used by process 1980
dpkg: error processing package intelmq (--remove):
 installed intelmq package post-removal script subprocess returned error exit status 8
dpkg: too many errors, stopping
Errors were encountered while processing:
 intelmq

The process in question was a bot. It is left to the user to stop the running bots, otherwise intelmq is not removable.

This likely needs a way to not only stop the bots, but kill them to ensure no bot is still running.
