The original sentence:
It is recognition of compassion’s part that leads the upholders of capital punishment to accuse the abolitionists of sentimentality in being more sorry for the murderer than for his victim.
My questions are:
Which one does "in being more sorry..." modify, "the abolitionists" or "sentimentality"? I would pick "the abolitionists."
Is it also fine to drop the preposition "in" before "being more sorry" as a state of being?
It is recognition of compassion’s part that leads the upholders of capital punishment to accuse the abolitionists of sentimentality being more sorry for the murderer than for his victim.
