He's only a tad bit innocent

I'm almost a little parts of me that wants to dislike Grendel because he is in fact a monster but then the other half is sad for him because he is just trying to fit in with the men so that maybe hell be apart of something. Grendel is obviously a monster who is not apart of the human world but rather threatens thems and terrorizes them. There was the time where he got his foot caught in between to the two tree trunks and that was where he first discovered man. In discovering man he seems that they and him are not that much different from each other in that they both speak the same language. What I'm confused about is whether or not Grendel is actually talking. We are reading his thoughts but we haven't actually heard hi, communicate. In the beginning when his foot gets stuck he tries to talk to them but they don't understand him or that he is trying it attack them or when he sees the dead man outside and he picks him up and throws him over his shoulder and runs into the meadhall and yells out" Mercy!Peace! Friend!" hes almost trying to ask for their forgivensee trying to connect with them but theynrejct him and think thatbhe is trying to attsck them.So then you begin to think that the whole story is just his thoughts, he has told us that he speaks the same language as the humans but then at the same time when he has tried to communicate with them it's not the same language . It is possible that he could just speak like his mother (she is always saying drool , drool) but thinks like the humans do. Which would make his mind very sophisticated. Then what confuses me even more is that when he is hiding in the forest and he talks about how Hrothgar has violence and shame etched into his face and Unferth is asleep but guarding the meadhall and he is just watching them then someone in the forest is asking who is there and he says " the Destroyer" it seems as if the priest can understand him and he can understand what Grendel is saying to him which makes no sense to me. I don't think that Grendel is necessarily evil, I think that he , like Adam and eve , has been influenced by evil to embrace his evil side. The evil side we all posess but must be pressured so that it comes out because before he was curious at the world and angry that was why he was attacking the meadhall but then he comes into his role after talking to the dragon and becomes "the Destroyer"
