You could have saved yourself some typing and just written "I'm selfish and wilfully ignorant"

First - educate yourself on communism, you clearly know nothing about it, but the fact that you're against it because "bloodshed" yet are openly in support of capitalism makes you nothing more than a wilfully ignorant hypocrite.

Capitalism has and continues to kill hundreds of millions (at least, in all the time it's existed) for profit in war, with hunger and restricted access to water, with homelessness and poverty, with preventable disease, all created and excused with the myth of artificial scarcity, with climate change, with immoral laws and entire systems designed to keep large segments of the population as slave labour, which is what they used to gain their power and wealth to be in the position to impose all of this in the first place. And all that just off the top of my head, there is so much more violence that is inflicted on us daily, they've just got most people, yourself included obviously, convinced that's just life, when it really really isn't. And those who actually benefit are never just going to give all of that up.

You keep mentioning the potential "sacrifice" which tells me just how privileged you are, but don't be mistaken - that privilege will only keep you safe for so long, and you not giving a shit about those of us who don't have it and are already suffering and dying under the system you're so eager to defend despite openly admitting to not understanding it (and displaying no understating of the alternative either), doesn't change the fact that said system is destroying the planet and everything on it, and no amount of bootlicking will save you from that.
