When the US intervenes in other country’s affairs, it always does so in pursuit of its own self-interest (or in pursuit of what the then adminstration considers the interests of the US).
(One qualification to that; conceivably the US may intervene in the affairs of another country because the then administration considers this to be in the best interests of the administration; confusing their own interests with the national interest is an occupational hazard for politicians. Be that as it may, the US never intervenes in another country out of a motivation to advance the other country’s interests.)
That doesn’t make their intervention wrong or damaging. The US may hope or expect that their intervention will be beneficial to the other country, even though that is not their motivation in intervening. And the intervention may indeed be beneficial. (Or it may not, of course.)
If “acting out of self-interest” = “being evil” then, yes, the US is evil. And, as a very powerful nation, it may be more evil than most, since it has more opportunity to act in the way that it considers will advance its interests than other nations do. But I don’t think this is a good definition of evil.
But if “acting in a way which is objectively harmful to others, in disregard of their interests” = “being evil” then the case is less clear-cut. Yes, the US has done this, but so have other nations. As other posters have pointed out, the US is not to be compared with, say, Nazi Germany in this regard.
