Most of the targets have good enough reasons that they should be killed. There was that one guy in Oblivion that was mostly just a [censored], but the vast majority are terrible human beings that will leave the world a better place with something stuck in their bellies. Whether that's a knife, a vial of poison, or an arrow is up to the player.
However, I suspect this was done so players that like to maintain some sense of integrity (like me) don't feel they have to choose between playing a completely evil character or skipping the faction quests entirely.
If I had to assess from a philosophical or ethical standpoint at any level, I would say that the Dark Brotherhood is amoral, or immoral, or both, through and through. It's not like Assassin's Creed where assassins supposedly kill in order to "protect the world." The Dark Brotherhood, regardless of its religious overtones and tenets, is a group of professional hitmen, nothing more, nothing less. They kill for money, and without any discernible purpose besides service to Sithis, it's impossible to even begin arguing about "good" or "bad" in the philosophical sense.
Judging from the quest lines in Oblivion and the sorry state Skyrim is in though, I'd say that at the very least, most of what the Dark Brotherhood does isn't that bad in terms of affecting the political landscape. Excepting of course...that one very, very important figure that you have to kill. I haven't gotten to that quest personally yet, so I can't comment.
