Sad sack of shit is someone who actually gets emotionally invested in an organization that he has no affiliation with and is comprised of people his own age making 10x more than him, ie you. I bet you paint your face and shit too lol, like the Eagles are something to be proud of anyway, Buffalo Bills's little brother
Saying apples to oranges probably isn't enough since you seem like the kind of person who actually needs a detailed breakdown of why they're stupid. After you realize what you said is worthless you can then pretend you were too good to get into an internet argument anyway or try to deflect in whatever other way you can think of.
Comparing it to drunk driving: One is a single choice made by an intoxicated mind that, while incredibly stupid and unacceptable is still very unlikely to produce harm. Choosing to drive drunk does not guarantee that harm will come. The other was a series of conscious decisions over years of time that were guaranteed to cause harm. If you choose to smash a dogs skull on the floor there is a 100% chance that you will smash a dog's head on the floor. If you choose to electrocute a dog there is a 100% chance that you will electrocute a dog. He enjoyed killing them and did because he felt victimized by their 'poor performance' in an activity that takes years worth of torture just to get them to engage in (not counting the untrained family pets he threw in there purely for fun)
Saying he changed: If he didn't get caught he would still be doing it today. Nothing about him has changed the only thing that has changed are the circumstances in his life which had to be forced upon him by the justice system and the public. He doesn't even issue his own statements, hes dumb as fuck and is incapable of change or any sort of mental progression beyond basic understanding and compliance when the world says 'you can not do this again or you will lose everything you have'
Saying he did his time: Yea because the court system is totally infallible and we should blindly form opinions solely on their rulings. most of his sentence was for gambling, not the psychotic behavior he displayed. Also who's to say it was even the correct sentence, it was one court, in one country. The sentence little to nothing to do with the morality of his actions. Completing a court ordered system doesn't automatically earn a second chance.
