Why do you disguise yourself as a moderate in politics? Are you in a country where being a communist is forbidden?
It depends on in which context you're organizing (e.g. are these petty-bourgeois people or workers?), but in my opinion, honesty is the best policy (with other workers at least). You'll never destigmatize the word "communist" if you're afraid to say it yourself. Also, with actual working people, you'd be surprised how many of them are desperate for a change that they'll consider communism.
Serious question, what's your thought process? I get removing them during war because they're a threat to the working class. Afterwards, when a worker's state has firmly been established, further deaths don't necessarily serve an end.
