I don't think that we can say of the Sadist character that he's solely motived by sadism. If self-gratification was his sole motivation, surely he would not be so picky about who he gratified his violent and sadistic urges on. You make it sound as if the decision to never do harm to the innocent either by word or deed was merely a quirk. Clearly there is some motivation their which is benevolent, so why on the basis of his personality are we judging him evil? And if indeed it is only a personal quirk, why in the world are we judging him lawful? For my part, the character sounds like a vaguely CG character with a rather extreme personality flaw that he is holding at least somewhat - and to the greater part that matters - in check. Now of course, there are as yet unrevealed aspects of his character and his relationship to the world that might alter that decision, but from what I've got to go on so far he sounds like a Vigillante of the more brutal 'pay evil according to its wages' mode. That on the neutral end of a broad CG spectrum.
Unless you're using BoVD and BoED- BoVD suggests that the truly sadistic- those who delight in inflicting suffering on others, are evil.
And BoED is of the "torture is always an evil act" type.
Fiendish Codex 2 also lists torture as always a corrupt act, and has "inflicting indescribable torture" as an act so evil as to be on a par with Murder For Pleasure.
CG isn't about being more willing to do Evil deeds than LG- it's about being more willing to go against authority than LG.
The character has two traits, both in immense strength- compassion toward the innocent (which is why he protects them and doesn't harm them) and hatred of the "not innocent"- defined by him as those who prey on the innocent.
To him, no atrocity is too vile to inflict on them.
And he knows that in the D&D world, torturing the evildoer as punishment is evil- his attitude is "then I'm evil and proud of it"
What makes him Lawful is his code.
Meanwhile your Crusader doesn't sound even remotely good to me. He doesn't seem to me to be much concerned with making war on evil, as he is utterly consumed with making war on his enemies. He seems to be cut entirely of the 'victory for my side at any cost mold', and that in my opinion is the defining trait of Lawful Evil. No doubt me maintains some sense of honor, and he believes (wrongly I think) that he's acting under the authority and commission of an external power (the aforementioned LG deity), but he seems to be rather less concerned about achieving good ends (the protection of the innocent) than he is about achieving victory. I therefore assert that from what I've been given to know, that he's LE.
What makes him possibly nonevil is that he has no sadism- he is concerned with protecting the innocent from "those who are evil". He never harms the innocent for profit, and never harms the innocent for fun.
What makes him nongood- is that he is very, very, pragmatic. He is all "needs of the many outweigh the needs of the few" and "to save innocents, sometimes other innocents must be sacrificed" and so on.
Not all "sacrifices of the innocent" count as murder- especially in war.
And yes, they are pretty opposite in a certain way.
Think of it as two principles "Do not harm the innocent- ever" and "Do not commit evil deeds and enjoy them- ever"
The LN guy has chucked out "Do not harm the innocent"
The LE guy has chucked out "Do not do evil deeds and enjoy them"
