If u run a yellow light and hit a pedestrian who is jaywalking.. who is at fault?

today i was on my way home from work and i ran a yellow light at 50 mph.. there was a pedestrian who decided that he would cross the street before the walk signal came on because according to him.. he was in a hurry to get to the other side and smoke a "phat" one.. i braked and he ended up with a few bruises on his knees. half of his bike was also totalled. So is it my fault or his fault? he was jaywalking and when i hit him.. the light had JUST turned red.. my fiance ended up coming to the rescue and paying him 250 for the bike. A couple of witnesses also said that they saw him almost get hit by another semi-truck a couple minutes before i came by. in my honest opinion i think this guy is out for money.. what do u think?
