sure, it’s a war and violence might be necessary, but it’s a question of proportionality. you don’t meet a peaceful protest with artillery fire either
you also seem to be under the belief that anyone who dissents or in any way acts against the will of the state are doing so because of foreign interference instead of simply from their own volition. in neither case do deserve to be killed unless they are themselves violent or otherwise explicitly soldiers. i guess a more common issue than powerhungriness among communist leaders is the related issue of extreme paranoia which leads to tons of innocent people being killed or imprisoned. this is an example of something that can be triggered by CIA, but not excused by CIAs actions
why do leninist states even have a singular leader in the top if they’re trying to abolish hierarchy? why not cap it off with a committee with some further safeguards to prevent the power from getting to their head instead?
i doubt you yourself believe that all the actions of people in the top of the party represents the class of the proletariat that they are trying to represent instead of a hybrid between that an actions to further the class they themselves are now in as elite party members. this issue is furthered by corruption which all communist states are vulnerable to (especially since they are initially centralizing a lot of power) and which a very large amount of precautions need to be taken against to prevent it from collapsing the system on its own even without outside interference. now, capitalism isn’t better with corruption since the system is essentially a case of legalizing corruption under a formal system, but that’s also why it doesn’t collapse from corruption
i don’t mind the bureaucracy of a communist state at all, i don’t see where you got that. just the extreme actions against any dissenting voices, especially since they usually are talking about some real problem that needs to be addressed rather than just destabilizing for the sake of destabilizing
i also hope that you agree that russia is no longer in any way a communist state?
