Inkblots

Every inkblot is a confession.
The first shows a child of nine stealing candy bars from the drugstore.
The second shows an angry teen setting fire to the home of the rival to his affections. Romeo burns. Juliet burns.
The third reveals another theft – test scores for his university admissions exam. A+!
The final one shows his business partner allowed to choke to death after a discussion about insurance.
Wait. There’s one more left, doc?
Hold still. Let’s see… that’s you. And me. Standing over you.
No idea how I kill you, but I’ll try to make it interesting.
