支持。贞观16年，唐太宗有下诏令皇太子出用库物不设上限。但这时的李承乾随着年岁渐长以及患了足疾，开始变得叛逆起来，不过是因事对父亲不满，就敢任性大胆到一连几个月不上朝，而唐太宗不仅对此没有任何的指责与批评，还特地将魏征任命为太子太师，意在告诉众人他是绝对不会废太子的。
就算后来李承乾犯下了谋反这等滔天大罪，唐太宗也不愿杀了这个儿子，朝中大臣也没人敢说太子谋反按律当斩之类的话。最后还是通事舍人来济进言说：“陛下不失为慈父，太子得尽天年，则善矣。”这才合了唐太宗的心意，最终谋反案的一干从犯全部被赐死，身为主犯的李承乾却保住了性命，只被废为了庶人。而来济也因此得到了唐太宗的看重，官职不断得到升迁，不久就任考功员外郎，次年便升迁至中书舍人，与令狐德棻等人共同撰写《晋书》。
李承乾虽然被废，但唐太宗为了儿子将来的安危考虑，在立新太子时以“泰立，承乾、晋王皆不存；晋王立，泰共承乾可无恙也”为由，果断立了年幼却性格温和的李治为太子，目的就要能够同时保住承乾、李泰、李治这三个心爱的儿子。
贞观18年12月，李承乾病逝，唐太宗为之废朝，并葬之以国公礼。唐玄宗开元27年，李承乾的嫡孙李适之出仕唐玄宗的左相，李适之因为祖父谋反被废，父亲李象又遭武后所黜，葬礼有阙，于是上疏请求归葬昭陵之阙内。唐玄宗遂下诏追赠李承乾为恒山王、荆州大都督，谥曰愍，陪葬昭陵；又一并追赠了李适之之父李象为越州都督、郇国公，伯父李厥及亡兄李玭等人也“并有褒赠”，“褒册典物，焜照都邑，行道为咨叹”。
事隔数十年后，李承乾终于重新回到了父母的身边，自此长眠于昭陵，永远陪伴在父母亲身侧，再也不分离。
