i think the reason why he made ichigo fight aizen was because what rhe soul society had plan for him. it was all made clear during the excursion arc. they soul society wanted to use him to bring out the other substitute soul reaper after which they would kill them both. Isshin was aware of this so to spare his son that faith he made him lose his powers...tho that back fired in the end since the other substitute soul reaper still contacted him.
