Noone has the right to do anything. At all. Not even breath.
We, as a race, have no rights, we never did, and I'm sure the day may come when we will not again.
We made them up y'see. Gave them to ourselves as justification for the choices we made and actions we took. They let us sleep better at night knowing we were 'right' and the other person was 'wrong'.
Take it back to the bare bones and it's all about capability and choice.
We are all capable of the most heinous of acts. Crimes by our own standards, but standards change. How long ago was it when you would have been talking about Homosexuals the way you talk about Paedophiles?
Go back and ask an adult male of Ancient Sparta how he feels about underage sex = standards change, capabilities don't.
So it's down to choice. Don't kid yourself about rights. It's choice, and it's only if enough people choose something that it's called right, or A Right.
If this guy gets the death sentence, it will be because the individuals of the Jury choose to see him dead because they didn't like the choices he made.
And so to go full circle and bring capability back into the mix - I wonder if they would make the same choice if they also then had to admit and release their own capability for violence. If they had to physically carry out the sentence and kill him.
Rights, law, right & wrong = whatever lets you sleep at night.
By the way, I'm not actually sure where I went with all that burbling - brain working + fingers typing = strange random posting.
