Lyric discussion by EmperorPear 

After thinking about this for some time, I believe that this is about a negative person who did bad stuff

Verse number one speaks about the person's presence. The vapor can mean literal vapor, or it can mean the person's elusiveness, his method of concealing his wrongs(Which seems to be ineffective). The sickness tells about the negative energy that this person emits.

The Second verse/Chorus has two possible meanings. The first two lines label the person, while the second two may reference the narrator's increase in being aloof, or the person's detachment from people.

Following this school of thought it's easy to interpret the remaining lyrics of the song.

Verse 3 is advice given to the person, to take a step back, see how he acts. "As on film, you will see the mask of shame" - Tells how seeing the shame on his face is as easy as spotting the villain on a film. The rest of the verse tells how, upon retrospection, he will see that he's undeserving of the social status he possesses.

The last verse is kind of tricky: The first line may peak about the person's rationalization of his works, or how he pulls stuff out of context to justify himself. The others may speak of the deed itself. The second in particular, how he didn't save someone when he should. The line above referring to status could come into play here, telling us how he has the power to stop something from happening, yet he didn't use it, ergo that power should be stripped from him. The final line may speak of the deed, or his own life after the event(s). Sick sleep - he can't get a good night's sleep from the weight of his aberration of a burden.

All in all, It's a very good song, that possibly carries this message, but nevertheless it gives of a melancholic, dark, almost inimical vibe that I simply adore!
