What works better, in your opinion?

Or, what system is not responsible for human atrocities?

There is a significant difference between socialism and communism, Americans seem to purposely conflate the two, they are not the same.

Haiti pulls that off under capitalism too. Wider context is a bigger part of that than who owns the means of production.

There are lots of socialist countries in the world that are doing fine.

Nordic style social democracy works quite well though. Communism sucks, but too much unregulated Capitalism isn't great either, as we can see in USA and many other countries that suffer from extreme inequality.

It's strange that someone mentions socialism and then another person replies saying communism doesn't work. Are these two the same for you?

Is this supposed to be an example of propaganda? The line that socialism killed millions uses the unfair standard of attributing wide categories of end-of-life to socialism but not to capitalism or Tsarism.

millions died due to exploitative labor practices by colonialist invaders exploiting the resources and cheap labor potential of the people in it yet I don't see you aknowledge that.

communism wasn't behind american slavery or the Belgian occupation of the congo.

Not a fan of communism but I dont' think unfettered capitalism is much better. both systems benefit a minority of people at the expense of the majority largely because they allow power to be concentrated in the hands of a few.

At this point, anyone spouting vitriole about communism and socialism like they are the same thing just come off as lacking basic capacity to understand nuance at best and mentally ill at worst.

Deliberate starvation is more of a capitalist thing. It's not like China or communist parts of India have a big famine problem, while the US and their partners are causing famines in e.g. West Asia right now.

Left wing policies actually work pretty well, this is why the US has spent so much resources undermining movements and states trying to implement them, and this is why the Soviet needed nuclear weapons to survive for as long as it did.
