Nearly crashed, what should I have done?

Okay so I was going down a road and this 2012 silver Honda Civic got really close to me and was tailgating me. I didn't say anything to the person in the passenger seat because then they would say, "You can't control what happens behind you, you can only control what happens in front of you." So then we started going to a light and it was turning yellow and we were far from the light. He starts honking at me many times. The light was solid red and I was making a right at the light. All of a sudden he went on the opposite side of the road (solid yellow line) and speeds RIGHT THROUGH THE LIGHT! Everyone was just sitting there watching him and I was really scared. I then made a right because there was no "No Turn On Red" sign. Then the person on the left of me started coming but he/she probably knew how scared I was so she started slowing down as I went right. He/She was far away though. If there was an accident with the Honda Civic, who would be at fault? Me for not getting out of the way or him for speeding and crossing a solid line at a red stop light and going through it or someone else that started going at the green light. I kind of know the answer but I just want to make sure.
