IT IS FUN TO KILL DWARVES IN INVENTIVE WAYS.
I think what you're trying to say is "
I, personally, think it is fun to kill dwarves in inventive ways." As you have no doubt noticed, some people disagree with that sentiment, and you will have no luck attempting to change their minds, especially if you persist in saying they have no imagination etc.
Personally, I don't kill (random) dwarfs in deathtraps for giggles, because it just doesn't seem to me to be the right thing to do, and I suspect I don't find it as funny as you clearly do; there's plenty of goblins, kittens, and so on in the world to disintegrate without resorting to dwarfs, anyway, and if you absolutely have to kill dwarfs, kill the ones who cause problems by mandating wierd stuff. A migrant dwarf can eventually become anything you like. A noble can't. My fortresses are population capped at whatever level gives me a reasonably consistent 30fps, which is roughly somewhere between 100 and 150 dwarfs.
I do not have a problem catering for any number of immigrants at any stage in building a fortress these days, really, the whole "problem" is a bit of a non-issue so far as I'm concerned.
What do I mean by that? There is no "immigrant problem" that needs to be "solved" by random slaughter. If you want to randomly slaughter dwarfs, go right ahead and do it, have fun, DF is for certain partly about blood and gore, but you're not "solving" a "problem" cause there ain't no problem to solve.
