AFAICT this dh_installinit snippet should always be successful; play
with the s-s-daemon options as necessary to ensure that it is.
Killing a process is always possible, even if one has to use kill -9.
Then there is --oknodo which you could add to the options for
s-s-daemon (stop) in /etc/init.d/fail2ban, such that it should never
return a nonzero exist code. I notice that /e/i.d/ssh (stop) uses
this, so it seems to be sufficiently conventional.
