Big guy pushes arguemt too far
Little guy feels threatened,
Little guy pulls knifs to make big guy back off
Big guy sees knife and tables are turned
Fight or flight kicks in and knowing flight is no option big guy fights
Little guy who would never stab anyone has no choice but to stab..
Stad someone once and nothing much happens.. Panic sets in and he keeps doing it
Probably tragic event.. Or maybe little guy just felt a little stabby and was out to murder anyway..
Why are you attempting to justify the attack?
There’s 2 outcomes imo, 1, he’s a murdering scumbag and should be jailed for life or 2, he’s mentally ill and dangerous and should be in a mental hospital for life
