I have a nice simple solution. To quote Kyo frm DEG… just blow his head off while he’s sleeping. But tht
poor ass may want to punish his dad for all the abuse, so he could
take him to a remote island, crucify him, then remove his
intestines with a screwdriver, then make his dad eat them. Then he
can do stuff lyk make his dad drink battery acid or stick hot metal
pokers up his ass, then leave his dad to die and his body to be
eaten by vultures.
