I appreciate the advice but his lack of respect stems from his poor upbringing. He was given virtually everything I wasn’t given and was always treated with blatant favoritism. That combined with him seeing me during my darkest years when I was dealing with extreme bullying and isolation caused him to lose all the respect he once had for me. He tries to act like a thug and before I left for college he always tried to pick fights with me due to his short temper. I’d never actually hit him however out of fear of my fathers retaliation as he’d always take my brother’s side. He’s allowed to do as he pleases and that has made him the lazy, selfish, confrontational, arrogant brat that he is today
