If you did it with no/few recent punishments (eg. warns, gags, mutes) then yes, but your definition of RDM and acceptable KOS reasons aren't entirely correct either.
RDM can be done by anyone, not just innocents, and the example of RDM is unclear, who is RDMing in the example you gave?
Also, the first acceptable KOS reason isn't really true, if someone is prop abusing you (get staff to) punish them accordingly, killing them is only a last resort
