well, he cant just leave his sister behind
yes he can
yes he can
He'll just get abused and exploited more :(
His sister will be just fine, it's not a case where even his sister is abused, of course she'll miss him but she'll be treated just fine in that family unlike the mc here...
Why not go with the merchant to travel with him? And leave that shitty place since you'll be exiled sooner anyway.
