As per the MB book nothing is mentioned about shakuni's motivation or reason for doing what he didBut after interpretations by scholars few theories or stories have been added.The most popular theories are1)He was angry with Bheeshm for marrying Gandhari off to a blind person he took it as an insult and henced vowed to destroy the thing Bheeshm treasured the most his family .Hence by ending Kuruvansh he acheived his aim.But like 'Justlikethat' and you pointed out he ended up hurting his sister as well.But that is the thing about revenge it makes you so blind you dont see whom all you are hurting in your path of revenge.That is why God's never bless an act of revenge2)Another version is that Bheeshm imprisoned his family and gave them no food to eat so that they die of starvation and only shakuni survived.If you go as per this version i would say Bheeshm got what he deserved when kuruvansh was destroyed completely
