Wish My Old Boss Pain And Suffering

I've been out of work since last November and have been struggling to get full time work since. All because of my manager from my old job, he treat people at my old workplace like shit, berating people for taking breaks due to illness and often yelling at employees in front of customers then due to management mishandling funds, three of us were let go due to 'budget restraints' we were given one weeks notice and two of us were told over the phone.
I have tried to reapply when desperate for work especially round the area but to no avail when he's there.
I hate him and his entire family and wish him nothing but suffering and pain
