It's a manga that has to be read and enjoyed slowly. There's something to ponder in every page, from the expressions on the characters' faces, to sentences that are in no way devoid of sense or used as a simple placeholder. Bearing in mind all the questions that this manga raises in regards to the morality of some situations (e.g. assisted suicide, murder in the name of revenge), the answers would be strictly personal and it'd feel wrong for me to describe any of the characters as "bad" or "good". There's no "right" or "wrong" way to interpret or regard this manga, and you will mostlikely find yourself holding different opinions on the characters, than the ones you started out with.

And that, in my opinion, is a great technique sadly underutilized in manga: reminding the reader that people aren't defined just by a single personality trait or (more importantly) through a single point of view. Every character presents themselves as the "hero" of their story and is later shown through the eyes of other characters with varying moral compasses of their own. It is at these points that the saying "we judge ourselves by our intentions and others by their actions" comes to mind.

Sometimes, the art looks messy - or rather unlike the clean, perfect characters you normally see in mainstream manga. Although slightly exaggerated, the characters in this look more on the normal side, albeit not as visually appealing as regular manga. All in all, the story is definitely the more important aspect, and I can let some art quirks slide in favor of it.
