In Of Mice and Men, what evidence suggests that Lennie mightbehave violently?

All I have is that he accidently kills the mice when they bite him when he pets them. I don't think that is enough evidence. Please help. Thanks.
(FYI- I've already looked at sparknotes and pink monkey)

Consider: At the beginning of the story, they were leaving an old job and going to a new one. Why were they always having to leave good jobs and find new ones???

Did you really study the "Characters" in those 2 sites? Lennie, note the last name "Small" is so ironic because he is huge, although large is mentally limited. He has no idea how strong he is. Note he accidentally kills Curley's wife, and mauls the mice, pup. He is totally unable to control or judge his own strength; possibly he is autistic.
