I think the second one's answer is so he could cook her. The sentences aren't listed chronologically. The last sentence really should be first, because he killed her, than set her to cook.
I agree with this answer but one thing should be changed about the riddle:
A man goes home at 4pm and see his wife cooking, he then goes take a nap and when he woke up (at 7pm) a marvelous dinner was prepared. At 10 pm they go to bed. In the morning at 7am, he killed her. Why? shouldn't it just be HE went to bed?
OH AND BY THE WAY IMPORTANT WAS CORRECT!
Here's a new riddle: WHAT's HIS JOB RIDDLE! A man was sitting at home watching TV. When it starts getting late(8PM) he turns off the TV and reads a book. At 10:30PM he goes into his kitchen, gets a glass of milk, turns out the lights, and goes to bed. When he wakes up in the morning he goes outside, picks up his paper, and reads the headline: 1,000 people die! Then he exclaims, "DEAR GOD I KILLED THEM!"
