I'm not sure where you get your information from, but Ben Hall wasn't known for giving to the poor, but he definitely knew what "stealing from the Rich was all about. His only semi charitable act was feeding a group of people who were in a pub whilst he robbed it, plus some town's people. That food actually belonged to the pub, he never paid for it. He did however give them a small amount "For their expenses" whatever that means. This and the feeding were probably carried out after he and his crew got drunk.
Ben hall was an extremely prolific thief (more than 100 robberies) who was shot multiple times and died for his crimes after being surprised by a squad of police after they were tipped off by a supposed friend of Hall.. One thing Hall wasn't, the type of person you'd take home to introduce to your family.
There were certainly no reasons to equate him to Robin Hood, a supposedly fictional character in the UK. That was where the infamous "Stole from the Rich and gave to the Poor" phrase originated.
Footnote: I didn't realize you were referring to Ben Hall, the use of initials eluded me.
