Satan Walking Into Gods Plot

Not in his favor eyes shifty But goes to his credit nifty, Helps not his image being hefty But mars it not being the thrifty... Not a nice story he's crafty, Rather that he's so at fifty, At their office his choice Mufti, Yet breaks not the rules held lofty So, the question: Nice Guy or Not: What has he for us Mankind got? Is he The Good with some bad blot: Satan walking into God's plot? Some had settled for "faintly good" Others asking for time to brood!
