Some pretty rough things have been said by conservatives about Michael Schiavo, especially on TV. For all I know he is indeed operating from the worst intentions here, but it is also quite possible that long ago he simply despaired of Terri recovering, which is what this passage from the Guardian Ad Litem report (linked to by Byron yesterday) tends to suggest:

After the malpractice case judgment, evidence of disaffection between the Schindlers and Michael Schiavo openly emerged for the first time. The Schindlers petitioned the courtto remove Michael as Guardian. They made allegations that he was not caring for Theresa, and that his behavior was disruptive to Theresa’s treatment and condition.
Proceedings concluded that there was no basis for the removal of Michael as Guardian. Further, it was determined that he had been very aggressive and attentive in his care of Theresa. His demanding concern for her well being and meticulous care by the nursing home earned him the characterization by the administrator as “a nursing home administrator’s nightmare”. It is notable that through more than thirteen years after Theresa’s collapse, she has never had a bedsore.
By 1994, Michael’s attitude and perspective about Theresa’s condition changed. During the previous four years, he had insistently held to the premise that Theresa could recover and the evidence is incontrovertible that he gave his heart and soul to her treatment and care. This was in the face of consistent medical reports indicating that there was little or no likelihood for her improvement.
In early 1994 Theresa contracted a urinary tract infection and Michael, in consultation with Theresa’s treating physician, elected not to treat the infection and simultaneously imposed a “do not resuscitate” order should Theresa experience cardiac arrest. When the nursing facility initiated an intervention to challenge this decision, Michael cancelled the orders. Following the incident involving the infection, Theresa was transferred to another skilled nursing facility.
Michael’s decision not to treat was based upon discussions and consultation with
Theresa’s doctor, and was predicated on his reasoned belief that there was no longer any hope for Theresa’s recovery. It had taken Michael more than three years to accommodate this reality and he was beginning to accept the idea of allowing Theresa to die naturally rather than remain in the non-cognitive, vegetative state. It took Michael a long time to consider the prospect of getting on with his life – something he was actively encouraged to do by the Schindlers, long before enmity tore them apart. He was even encouraged by the Schindlers to date, and introduced his in-law family to women he was dating. But
this was just prior to the malpractice case ending.
