Not quite. Dont get me wrong capitalism sucks and we should get rid of it, but for example colonialism is older than capitalism and part of its cause. So is colonialsim the root cause of evil? not quite again before colonialism there where still a lot of repressive and very hierarchical societies so again to frame capitalism as the root of all evil is ignoring a whole bunch of other repressive systems that are older but are certainly strengthend by it.
So if you want to simplisticly frame something as the root cause of evil then it would be “opressive hierarchies are the root cause of evil”. but maybe im biased here since im an anarchist
Leftist are not a homogenous group, and there is a lot of criticism from people on the radical left of those authoritarian systems.
There is also a few people who dont and that glorify authoratarian aspects of communism There is also a lot of nuanced positions you cant just simplify as The Leftist as if the loose association of movements and idiologies are all a homogenoud mass
