「constructive treasons」は「constructive treason」の複数形です。provided English meaning indicates it is the plural form rather than a new meaning translation. In Japanese, this can be understood as the plural (複数形) of the noun 「constructive treason」, where 「treason」 generally means 「反逆罪」, but note that "constructive" as a qualifier does not have a widely established equivalent in Japanese. Hence, the focus is on indicating its plural nature.
