Charateristics
They are ghosts, who have had some great wrong done to them in there lives, this causes them to remain behind after death, to try and avenge this wrong. Overtime they slowly become obsesed with this till, it is the only thing they can think of, Bobby discribed it like "an itch, that you just can't scratch". As such they act violently to try and avenge the wrong, however in the proccess, there obsestion with the wrong, can (and often) leads to them harming innocent people. Sometimes there vengence can spread on to others, who had nothing to do with them, but have or are doing something that is similiar to there death.

It is possible, that once they are avenged that they pass on, however often they are unable to cause this. Ocasionally, there people who are still alive, but on the verge of death.
