Answer:
Yes, it makes him seem more sympathetic.
Step-by-step explanation:
The perspective John Gardner used to describe Grendel made readers see Grendel as someone with feelings, much like every other human.
Contrary to what people originally thought of Grendel, Gardner shows him in a different light because we discover that he is not the blood thirsty monster we think he is, but he is empathetic to humans.
According to this perspective, Grendel's character was developed to show that he was lonely sometimes, even sad, and occasionally angry and even thought the humans were the monsters who he had to defend himself against.
