Intent matters.
It is clear that this man's intent was not to defend his home, but to kill intruders. Hence the tarp. Hence making the home more enticing for intruders. Hence the jamming equipment. Hence the not calling the police. Hence the multitude of statements he made to police. Hence the multitude of statements he recorded himself about his thoughts. Hence the taunts he made while he was committing the murders. Hence the calm wait for 10 minutes after he killed the boy for his next vicitm to show up. Hence the manner in which he executed both individuals. Hence the preparation for the entire situation.

This is the sound of a woman who wants to defend herself and family.

This is the sound of a man who wants to murder his enemies.
Both involve people breaking in. In the former, a woman did not entice a break in, nor did she want, desire, or pursue a situation where she was victimized, endangered, or cornered into killing. In the latter, a man enticed a break in, out of want, desire, and pursuit of a situation where he could be victimized, endangered, and given an excuse, a pretense, to kill.
In the former, a woman used her property as a baricade to shield herself from harm initially. In the latter, a man took precautions to prevent stains upon his property from the human blood he would spill upon it.
In the former, a woman warned an intruder not to enter. In the latter, a man calmly sat in his basement, waiting for the opportunity where he could finally take out some bad guys with a surprise attack.
In the former, a woman was in contact with an emergency dispatcher, asking for asistance along the way. In the latter, a man acted on his own, without any regard for involving, deferring to, or consulting the police.
In the former, a woman was clearly troubled by the act of killing someone, and did so with great reservations, regret, and remorse. In the latter, a man took great joy and pleasure in the act of killing, with great anticipation.
Though both killed individuals who unlawfully enterd their property with malicious intent, one acted in a sound manner in accordance with the law and deserving of its mercy.
One acted in a deranged manner with murderous intent and a blatant disregard for the law, and is deserving of nothing less than prosecution and conviction to the full extent of the law.
