Plenty of people have been murdered to defend capitalism. After the fall of the Paris commune, 30000 people were butchered in the streets. Millions of people were murdered for being communist or even just belonging to a union in Indonesia.

Not to mention the fact that the 100 million figures includes Wehrmacht soldiers or terminated fetuses as "victims" of Communism to inflate its numbers.

If you really think that there simply aren't enough resources for everyone, that makes the gluttony of the wealthy so much worse.
