The Beggars

After reading "The Beggars", I was wondering if Wordsworth wanted us to feel pity for the two children at the end of the poem or feel resentment for their mischievous ways. He paints a sad picture of the two boys' mother, a woman who is awkwardly tall, has tanned skin from (as I understood) hard labor in the sun, and is a beggar. The narrator does help the woman by giving her bread and, then, proceeds on to the boys. So, we are under the impression that the boys are poor and underprivileged. But when they tried to trick the narrator and lied to him about their mother, how does Wordsworth want us to view them? Pity them as poor, desperate boys or resent them for their dark intentions. The poem ends without any more information about the narrator's thoughts about the whole situation. All we know is that the narrator was aware of the lies of the two boys. Also, was this some sort of socioeconomic critique in the form of a poem or is it just a story about some simple event that happened in Wordsworth's life?
