 Bobby's most defining character trait was his altruistic desire to do the right thing.This almost always put him in the cross-hairs of his older brother JR, who was known as a conniving and ruthless oilman.Bobby did on many occasions use ruthless tactics in failed attempts to beat J.R. Bobby was one of few people openly to take a stand against J.R. on numerous occasions (at times physically), yet the two never forgot they were brothers.
