The 1830 typesetter accidentally omitted the present participial persecuting here in this list of participial clauses. Clearly there would have been no motivation for either adding the word earlier on in the transmission of the text or for omitting it in the 1830 edition. In accord with the reading in 𝓟, the 1908 RLDS edition correctly restored the word to the RLDS text. For the same reason, the 1981 LDS edition restored persecuting to the list.
Summary: Maintain in Alma 1:32 the original inclusion of persecuting in the list of evil acts.
