The plots and hindrances were such that anyone would have been torn between blaming the parents or sympathizing for them.
We sympathize with and not for someone. Also, when BETWEEN is used, AND is used, not OR to separate the two options. For the first phrase, facts and circumstances fits well. Plots and hindrances are created and such creations would not put anyone in a situation that he/she torn between blaming and sympathizing. The spot on facts and true incidents would only put anyone in such a situation.
