Is this a good idea for a story/novel?

great story idea wonderfully put even for a summary! I would tell how the main character strives to fix everything and all the hardships that he faces. Also tell how he ends up bringing back the world as they knew it as it were and let them figure out what went wrong. Great story idea good luck! Also even the main character meeting someone and falling in love again after he murdered his wife would be great and if you could tell how and why like in a flash back or something would help. Have him meet face to face with his murderous version and settle things once and for all! Again Good Luck hope you found what you were looking for! Another idea you could have flashes between the main character and his murderous version to show whats going on while the main character is away. Have the main character battle to keep his sanity in his messed up world but help him combat it in the end!
