Can i do anything to help?

im 21, and am engaged with my first child on the way (6months pregnant). I have 2 younger brothers the middle one whose 19 as of a few days ago. he graduated high school about 6months ago my parents are trying to get him to do something with his life anything even get a dead end job they would be happy but all he does is play computer games and has no ambition to do anything, my parents are old now dads 58 moms 50 and the iron rule isn't so hard anymore. they don't know what to do they try everything but he's quite intelligent and gets around most things computer related (blockers, passwords etc) that they put on his computer, he complains hes tried to look for work and or schooling options and so on but what my parents say is he hasn't. My dad plans on kicking him out in spring and he will go through with it but my mom doesn't want him kicked out she wants him to ask least have somewhere to go or at least someway of supporting himself before. I live 5hrs away in a town with alot more work available. I want to help him out but the issue is i don't know if he wants to help himself enough, i work hard and make a decent amount of money and we have lots of toys half of which we barely use, but im worried that if i give him the option to come live with us for a bit to find a job, will i be looking after another person not helping someone out but having another child pretty much (i don't even have one yet), but i know if i don't do anything im pretty sure my parents will split over this, every time i see the family (twice in the last 6months) the tension is retarded i can tell there's gonna be a blow up and its all because of him so what do i, do i get him out of there and try to set him up for life. do i tell him to grow a pair and man up, to i coddle him and encourage him from a distance, or do i just stand back and watch everything crash
