"What a BASTARD he is an MONSTER I am so happy he was held accountable."
Are people bastards and monsters, and should one be happy for possible death sentences? As for me, I think often pure luck or chance or circumstances or whatever prevents one person from committing something terrible - that there is only a thin border line separating one seemingly "good" person from at one specific instance do something that would have made him a "monster" or "bastard". A restraint in a fraction of a second - and one is not a "monster", but a "good" guy. Longo also has a mother, and she has cared for him, nursed him, played with him, read to him, laughed together with him, and made plans for him and his future, had dreams about how good it would all be - and she must be heartbroken now.
I have a child, I made such plans, I had such moments - now that child is a drug addict, a criminal, and surely by many "SheilaM"s considered a "bastard" and a "monster" - but I look beyond that outer appearance, and inside of him I see that young child, those moments, and while lamenting those moments lost and that present appearance, I know that the person is no more a "monster" than I am, that a few bad decisions made at crucial times when the mind was temporarily blurred made a path which was afterwards so hard to change.
Longo was a child. He has a mother. He is no monster or bastard. He is just a scared child who made unwise decisions - with terrible consequences for innocent people, but monster - no. Give him psychological treatment in an institution, don't kill the mothers' children.
