What is the tone of paragraph 5

The tone of the fifth paragraph is one of agitation. The widow won't let Huck smoke.... and he considers her to be judgmental. 

Pretty soon I wanted to smoke, and asked the widow to let me.  But she wouldn't.  She said it was a mean practice and wasn't clean, and I must try to not do it any more.  That is just the way with some people.  They get down on a thing when they don't know nothing about it.  Here she was a-bothering about Moses, which was no kin to her, and no use to anybody, being gone, you see, yet finding a power of fault with me for doing a thing that had some good in it.  And she took snuff, too; of course that was all right, because she done it herself.
