If your worst enemy had died and you attended the funeral to say a few words in remembrance. It's likely an acquaintance of your fallen enemy would strike at you in vengeance.
So let's say your worst enemy has died and before the funeral service, you kill all of their acquaintances so as to avoid trouble at the funeral. A family member would probably disapprove of your presence.
Okay so the reason the two of you are enemies is because your enemy slept with your spouse and in retaliation you burned their family alive. So now, in victory, you have gone to the funeral service to say a few words before defecating on the grave and having a wank to celebrate.
Probably best you kill the priest too, witnesses and all that.
Memorial is those words, You Fuck is the celebratory wank.
If one wishes to find themselves the best allies to help spread The Infection, it is only reasonable to start with the Best Nation in the world. North Korea Best Korea! WANK
