Sound like EITHER way would be wrong. Whether someone is sealed or not, it's STILL someone else's wife. However, I don't blame Joseph Smith for doing what he needed to do. Solomon had lots of wives and concubines. We don't fully obey what the Prophets say, for example, the Prophet Joseph Smith wrote in articles 12 of the Articles of Faith that we are to sustain the laws of the land. Given the current debacle over illegal immigration, it's obvious that article #12 has been totally ignored. So, sometimes, things just "happen" as the case of marrying other people's wives an that was so long ago...Irrelevant today. Sometimes we just ignore the laws of the land or laws, period. It's unfortunate, but that's what people do.
