汉武帝明知道刘据冤死，为什么仍不善待其后人刘病已呢？
为何汉武帝还不善待其后人？

汉武帝最心爱的儿子便是戾太子刘据，可惜汉武帝晚年听信了小人对戾太子刘据的诬告，最后刘据怕不能自辩清白起兵自保，最后兵败自杀。虽然很多年以后汉武帝知道真相之后，追悔莫及并且建造思子台缅怀戾太子刘据，可是当时汉武帝已经有了新的太子，所以汉武帝对戾太子的后人刘病已没有太多优待，怕的就是戾太子的后人会威胁到新太子登基，动摇大汉的国本。
汉朝的时候还是父死子继的继位制度，当时戾太子刘据已死之后，那么戾太子一族的人便没有多大可能会承袭帝位。并且当时因为汉武帝对于戾太子起兵一事非常生气，还诛杀了戾太子的子嗣，刘病已是因为当时刚刚出生，所以才逃过一劫，可是幼年的刘病已便被汉武帝下到大牢之中。即便后来戾太子被平反，但是当时汉武帝已经有了新太子，而且刘病已非常年幼，不管从什么角度来说，刘病已都不可能继承帝位。
虽然刘病已没有可能继承帝位，但是他皇曾孙的地位却是非常容易被人利用的。当时汉武帝已经给戾太子刘据平反，刘病已作为戾太子一族唯一一个子嗣，便是汉武帝最嫡亲的正统。可是当时汉武帝已经有了刘弗陵这个太子，当时这个太子刘弗陵年纪也不大，所以汉武帝会担心他死后太子刘弗陵的帝位可不可以做得稳当。而皇曾孙刘病已便是一个不安因素。
因此汉武帝虽然后来为戾太子刘据平反，但是并没有给予刘病已太多的优待，只是恢复了他皇室宗亲的身份，当时刘病已和一般平民无疑，这也是汉武帝为了断绝有人利用刘病已身份大做文章。
汉武帝查明真相，知道太子冤死，还建立了思子宫，颁布了罪己诏。可就算如此，武帝也没有关照刘据唯一的后人刘病已，只是在遗诏中提到将刘病已收养于掖庭，并令宗正将刘病已录入皇家宗谱，自此之后刘病已的皇族身份才得到法律上的承认。
首先，太子刘据有罪，他有造反的实力，其次，汉武帝还喜欢刘据，就是有风言风语也不会有事，既然不喜欢太子，更何况刘病已，最后，刘病已是刘据死后才出生的，就算长大也不会记得这事，帝王可以不顾亲情，但是不能不要名声，不说百姓，也有百官，善待刘病已不是说自己错了，杀了刘病已又是一波声讨，那就只能不管不顾。
虽然汉武帝查明真相，知道太子冤死，也没有善待其后人，是因为汉武帝已经有了新的太子，怕他会威胁到新太子登基。
