There are lots of times when people either take stock of things, or they naturally evolve a bit.
It's really more simple than you're making it out to be: If you still like something, cool- if you no longer enjoy what used to be a favorite hobby/interest, don't sweat it. That's life. You adopt new things to like, you shrug off old ones. It happens to pretty much everyone- you're just
very aware of it because these changes are a direct result of your own intentional personal change.
Because you're initiating the change, you're going to be very aware of every issue that arises from it- but that doesn't mean they're bad things. If you lose interest, you lose interest... liking sports or video games doesn't make you who you are- it's just what you like.
I mean, I've never seen the point in knowing stats and getting all bent out of shape over a team, so sports have never interested me that much. Video games, though, are right up my alley because, in all honesty, I enjoy the "lazy time" of doing nothing. I also REALLY enjoy dark humor even though I'm a happy, outgoing, very positive person. I just LOVE dark humor- the more messed up, the better.
If you think your love of dark humor exists because of undesirable pre-existing thought processes, then that's fine- but if you resolve the thought processes you're concerned with, and still find dark humor funny, then obviously your love of dark humor wasn't born of your negativity. You just happened to love dark humor AND be negative, though the two ultimately proved to be unrelated.
In short... "let it be".
