There are no truly lawful good characters in RPGs anyway - they all carry lethal weapons and/or spells and don't seem overly bothered about taking lives. A truly lawful good character would rely on charisma, diplomacy, or even bluff checks to avoid combat entirely. Or reinforced back armour for when they have to run away from a fight they can't avoid.
I've always found paladins to be particularly hypocritical. "Look at me - I'm a paragon of virtue. Just ignore the gore-soaked weapon in my hand..."
You have some serious misconceptions about D&D morality systems and paladins. You should take the time to read the Book of Exalted Deeds if you want to understand how it actually works. It is one of the 3.5 supplement books, although a mature rated title. Part of your issue might be a Christian centered view on morality combined with the whole non-killing heroes vibe a lot of modern super-hero characters, like Superman and Batman, pull off. Lawful good tends to be more pragmatic than that in D&D.
Part of it comes down to the idea that killing evil, even redeemable evil, is not evil, nor is killing in self-defense or the defense of others who are good or others who are innocent, even if the enemy isn't evil, just misguided. The paladin is not meant to be a martyr who will sacrifice their own safety to take chances to redeem the enemy.
There are also numerous falacies involved in the way people like to discount paladins. The whole 'orc/goblin/mind-flayer/demon babies' thing is one of the big ones. In the case of mind-flayers and demons, they are 'born' fully mature and irredeemably evil, there is no babies in the first place, while there is an exalted spell in the Book of Exalted Deeds that can turn them good, it really transforms them into another type of being when it comes down to it, and it isn't truly a willing redemption, regardless of being a 'true' and permanent effect. The orcs and goblins are only 'usually evil', you should not be killing the babies, but you shouldn't spare the adults who might be attacking a village or something just because you are worried about killing their parents will leave them abandoned or something. If it comes down to it, you can go and take the babies back to your church to be raised as orphans, and preferably among a good, rather than evil culture, although this might not overcome their savage instincts. The paladin's job is as a warrior anyway, if some goblin tribe is attacking other villages because they won't make it through the winter without stealing food, this doesn't make their behavior excuseable, partly because the origins of this behavior lie in the fact that they don't try to properly farm and stuff themselves, and being a paladin is about fighting them in defense of the village, not about making sure everyone survives the winter. There might be another lawful good character who _is_ concerned about that, such as a cleric of some god of plenty or survival or something, but at most, the paladin should be alerting the cleric of some starving goblin village, not letting the goblins through to attack the village just because they won't survive without the stolen food. Especially in the case of goblins actually, because many goblin cultures tend to treat other intelligent humanoids, including other goblins, as a food source.
The paladin does not also go around scanning for evil with their detect evil and killing anyone who registers, the paladin's lawful aspect means they need to be reasonably sure this person is actively doing something bad, like they've been assasinating people or stealing from starving families, and the paladin should be trying to work within the bounds of the law in orderly scocieties if they can. They aren't allowed to kill someone who is 'evil' just because they are a selfish jerk, but hasn't really done anything truly worthy of being slain over, like murder, rape, or such.
It's a bunch of complex issues, and I'm not doing it justice as the Book of Exalted Deeds did, but I hope I expressed the gist of it.
Partly back to the thread's initial topic, I don't like the idea of playing evil as well, although for me it is often less about the evil and more about my own tastes, intelligence, and pragmatism, partly because a lot of the 'evil' in most games tends to come out as rather short-sighted 'evil stupid', or lacks any appeal in the first place, at least for me. They also tend to do good and chaotic very poorly at times, but usually do better justice to good than any of the other alignments, lawful, evil, or chaotic. They do pretty terribly for neutral, although this is more of a game mechanics and subtle issue. Games are supposed to be fun, so if an alignment isn't fun for you in the game, don't play it.
