I did not strive to controul them
The power of the Creature's rage is shocking, perhaps as well to
himself after having spent an entire year in isolation and under
a regimen of strict and carefully enforced self-control. The infinitive,
however, reminds us how severely that control has been earlier exercised
by him. It might likewise call to mind the lack of restraint with which
Victor Frankenstein pursued the researches that resulted in the Creature's
birth (1.3.3).
