Yep, there are plenty of critters doing "evil" typed damage, such as Unholy or Pure Evil effects on their weapons. To top it off, some of the best melee gear, such as the Litany of the Dead, Marilith Chain, or Chaos Blade all are evil tainted or true chaos, giving negative levels to lawful or good characters. It's part of the reason Paladins are on the bottom rung in comparison to other classes in game. They not only have lower hitpoints and poorer to-hit scores, and significantly lower damage output compared to other melees, they can't even wear the best melee gear without being hit with multiple negative levels.
Lawful isn't as much of an issue, since there's not as much chaotic damage flying around like evil. Monks are helped further by the fact that they can't use most of the good melee gear anyway, so are largely unaffected by the negative levels. Plus they're not really gear bound like most melee, getting their main damage from class abilities and not weapons.
I usually go Chaotic for the absolute minimum damage from alignment based effects. Lawful damage is exceedingly rare, I can only think of a couple of places where casters cast Order's Wrath at you. Finally, I can use True Chaos weapons without issue, and there are a LOT of lawful enemies, even if not a lot of lawful damage coming in.
Mureall is now 11, and is wearing the Sora Kell set (not upgraded). Still have to rerun Shadow Crypt for my Silver Flame necklace upgrade to deathblock. Just don't want to reflag for it.
I did buy a Deathblock robe, but that takes away my heavy fort robe. Not much more gear to grab, actually. I'll want a Con6/GFL belt from Shavarath, and a smiting/CGB wrap, upgrade the Sora Kell set, and a Resistance 5 cloak. At 13 I'll be using a Resistance 4 cloak at least.
