"I Kept My Promise"?
yes--it's all about his getting the last word... not only did he get the last word in regards to her life (in this life time... i do believe in a final judgment day)... but he had to put the final words--his words--there on her grave marker... he could have paid tribute to her with "i will always love you," or "i miss you," or something of that sort... but no... "i kept my promise." it's all about his sick self...
