Repair bent frame on 2005 660 Grizzly?

A few months ago, I got on my Grizzly and started the bike. Once I placed it in gear and started to move/turn, the throttle went wide open and could not stop it. It was late evening and by the time I was able to find the kill switch, I already ran into a tree resulting in 4 broke ribs. Today I took my first look at the damage and appears to have bent the frame as the right wheel which took the impact is shifted to the rear ~2-3". I raised the bike and removed the guards from the bottom and found the area that appears to took the brunt of the impact resulting in bent frame. Question is, should I attempt to repair/rebend the frame? If so any suggestions or other options? I have attached pictures showing damage. Any help or suggestions appreciated!
