Maine Coon Shot with a .22 Rifle

X Ray of cat leg shattered by .22 bullet
Quentin is a rescue, rescued from my back yard this winter. I thought at first he was a Raccoon because of his size. I turned on the deck light and realized he was a Maine Coon eating bird seed under my feeder. When I watched him walk I noticed a limp. I went outside with a bowl of cat food and called to him.
He talked up a storm to me and limped my direction. I coaxed him into the garage and he was lovable and friendly. The next day I took him to my vet and he was full of fleas (he slept with me that night away from my other cats lol) and also had a tapeworm.
Right now I am debating whether or not to get his leg fixed. My veterinarian said he was shot 3 to 6 months ago. He is approximately a year to year and a half old and a wonderful family member now.
I don’t know if fixing it would be to his benefit you can see by the X-ray it was pretty shattered. I don’t want to put him through any more trauma and would appreciate some opinions.
Thank you…
