Honestly I think the fiat gains are not very important to those people anymore. They are well past the point where diminishing marginal utility of money becomes a reality. They are, however, certainly interested in power as a greater concept, they are Malthusian in their worldview (as in they believe a large % of the human population either must or is doomed to perish), and they are delusional enough to think they can negate the laws of nature (or of God) with sheer will, imposition of rules and micro-management of other people. Is that evil? Explicitly, no. Implicitly, yes. At the very least, it leads to evil outcomes.
Now I'm talking about the 0.01% of people. The 1% are most likely more just playing the game & feeling good about winning at it, at least good enough to not question the very nature of the game and its rules. Is that evil? It's definitely willful blindness. Is that evil? Again, I would say it's not evil per se, but leads to it. It's a failure to contend with the nature of reality, which is a failure to embrace life, which is a sin, which leads to evil.
