I don't know what you're inviting me to make of the image; but I don't feel that it contradicts my point.
You seem to have a very deep concern about vicious and immoral paladins. If the concern is about mere possibility, I'd suggest that you relax. If it's driven by actual experience, then as I've posted I think there's something going wrong either with the circles of RPGers you move in, or with the games that you're participating in.
Dude, I've likely been playing since before you were born. I cut my teeth on AD&D and BECMI in the early 80's. I've literally played at hundreds of tables across nearly 40 years and three continents, across 5 editions of the game (skipping one).
PC's with 'Good' on their character sheet, and then proceeding to be very Evil (and then attempting to justify it to the DM) is not a rare phenomenon. It's actually incredibly common.
Our game rewards violence. Literally. With XP. Its the game currency to advance your character. Killing things and taking their stuff is the central core of the game. The game is built around violence, with abilities having mostly combat effects. It's also a game played by mostly immature young men (and boys) raised on 'action hero' mentality where brutally dismembering your opponent with an axe while sparing the time for a witty one liner is 'good', in an environment (a fictional game) where actually displaying any empathy for a NPC is a near impossible task, even for a well adjusted person.
Look at any alignment thread (including this one) in the history of the internet, and you get two clear camps form:
1) The ends justify the means and Lawful means following the laws. These are the dudes that want to apply a Chaotic Good alignment to the Punisher.
2) The road to hell is paved with good intentions, and 'Lawful' means following a strict code of conduct - not necessarily the law of the land. These dudes (and I am one of them) rate the Punisher as LE.
You then see the twits in Camp 1 start to condone even genocide, murder, torture, filicide, infanticide, mass killings etc as something a 'morally good' person can engage in, and the argument grinds to it's inevitable stupid and pointless insults and madness.
Every. Single. Thread. And nearly at every single table of new players I've ever had (and I've had hundreds of groups).
This doesn't make alignment 'pointless' as a tool though, as some people in this thread are suggesting. It just means the DM has to (at session zero)
clearly establish which of those two definitions of alignment apply, ensure his players know clearly when selecting their alignments, and and repercussions or ramifications of stepping outside those bounds (if any).
All this other talk is just meaningless waffle really that's been done a billion times before in a billion other threads. But you guys do you.
