It was just his cowardliness which made him stay for so long in a job he loathed.
On the first years, he developed migrain and eczema, later ulcer disease and convulsions, but what finally killed him was the "ghost of hate" (as he called it in the diary he secretly wrote on accounting books).
This comic was made for a contest in Serbia. It took me a long time to write it, given that english is not my first language and I took the Song of the Nibelungs as a model for the verses.
I guess I fell far from winning, but at least it left me with some work to show.
You can download the .pdf file with the whole comic through the link at the end of this post.
