Dante "built" his version of hell utilizing rather equal measures of Roman Catholic doctrine and his own personal perspective (sometimes rather vindictive) regarding the guilt or sins of the people he put there. Pick one character who seems to be in hell for reasons the Catholic church of the time would approve, and one who seems to be there simply because Dante was "getting even." Explain how this is so in each case using details from the poem (as well as from whatever historical sources you wish to reference).
