Requiring a Google+ account probably still doesn't rise to those levels, but it's a lot closer.

I'm not saying that annoying people by forcing G+/YT integration is evil. But presuming that an annoyance to you is an annoyance to all is faulty.
Why is Google being singled out here?
Whether that qualifies as "evil" is semantics, but excusing it with a comparison to puppy kicking isn't valid. It's a fundamentally different kind of issue and requires a fundamentally different kind of reasoning.
(Also, presumably "half the people you happen to know who joined G+ that you circled" has some selection bias to it.)
The launch of Buzz was definitely somewhere on the thoughtless-evil spectrum, though. A major breach of trust, at the very least.
If it was greedy, annoying, and user-hostile, then yes--according to the context of Google's motto[1]--it could be considered evil. "Evil" in this case doesn't mean the same thing it does when we're talking about rapists, murderers, and Dow Chemical.
Well, Google did buy a company that makes military robots....
