He hasn't done his time he has only served half of his sentence.
all those who go on their holidays do not fulfill the alloted time , they all serve less for good behaviour, along with also depending on whether the jails need the space, is he any worse than a drunk driver knowing fine well he's over the top and killing someone in the process, then also being released early.
If your question was directed at me then no he's no worse. Though the debate is probably in the premeditation of his act. I was merely highlighting he hasn't completed his sentence yet.
