It was actually self defense, and that other clip has nothing to do with this. Unfortunately my shadow play crashed so I cannot share my perspective.

Just to add my part, I was a hitman and decided to go down the bank vault when I was greeted by JMT who tried to open fire on me, I then equipped my jug so I wouldn't die and killed him, then Yeet Man tries to gluon me but fails really hard so I kill him.
