Personally i think it’s a bit of both. Sinbad likes power to safe guard his assets, and Morgiana, Aladdin and Alibaba just happened to fall into his lap on his trip to Balbadd!

But at the same time, the 3 of them give him nostalgia, he does long pauses, he knows what he’s become when it involves using other people to protect what he wants to protect, and have what he wants to have. They remind him of who he was before the bitterness of life took hold.

When he first met Morgiana and Aladdin and before he knew Alibaba was the Prince, and before he knew Aladdin was a Magi, he wanted to help Balbadd because he cared and repected King Rashid. He already planned to help Balbadd before knowing what Aladdin was.
