Janos Slynt can be seen as a man who is very proud of his power. He commanded the city watch when he was in the King's Landing and then he was transferred to the Night's watch. In Night's watch he was a close adviser to Ser Alliser Thorne, the acting Lord Commander after Lord Commander Jeor Mormont's death.
Janos Slynt can be seen as someone who do not take orders and who is proud of what he did some years ago in the city. He even thought that he deserved a better respect than any other looters, theives, or any high-born on the Night's watch.
Further, Janos Slynt, at an occasion, denied the command from Lord Commander Jon Snow and faces his death. Anyhow we can say that it was a good end for a bad character.
To recapitulate, Janos Slynt met a perfect death which was suitable for his character.
