How to handle the "Good vs. Lawful" thing?

How can I make a "Good vs. Lawful" dilemma feels emotional impactful to the players?
A lot of times I see the GM made the mistake of unequal exchange when it came to this matter – The PC usually lost personal things such as (stats notwithstanding) perks, honnour, job, etc if they choose to be Good, things that actually matter little if you see the way people playing Good-aligned PC. They have little qualm doing so.

Lesser of two evils?

Make the choice complicated or some shit.
Kill a child to save the village, something like that maybe.

Push them into a grey area.

"Lawful" does not mean "Law Abiding"

It's a difficult choice. Paladins are hard to play in this regard if the other party members are less morally just. The way I play it is that there is a greater evil at work, so I overlook their smaller misdemeanours for the moment because they are useful in our fight against the greater evil.

As I understand it, you're asking for meaningful consequences of chosing Good over Law.
Going against Law means becoming a pariah
Brand them with a stigma, making guards chase them, kids stone them and merchants refuse their gold, where they have to hunt their food and sleep in a leprosery.
Location varies depending on how much you want to fuck with them : Chest or palm are easy to hide, cheek not so much.

Take Zorro and Robin Hood: Both have to escape authorities constantly.

Someone post the screencap

Yeah, this is mostly what can be done.

But I think user here is asking for emotional impact (as in crafting a good narrative that indulge the players) instead of just a gameplay persepective.

The things you just listed will not make your players think more when presented with that kind of problem - they do not experience that kind of stigmata directly.

>emotional impact (as in crafting a good narrative that indulge the players)
It takes the kind of a player that can both understand the moral ambiguity behind it and show it through character's actions.
People used to working with the "classic" 3x3 alignment grid will usually not be that kind of a player.

emotional impact would mostly be created by opposing the results, i.e. a LN and a NG society.
Because making the player's choices durably impact culture and result in a less prosperous but ultimately more moral society is beyond the scope of most campaigns.

Have a reasonable authority figure become a potential enemy if the player chooses good over law.

Work with incomplete information, so that from the POV of the authority figure, they are making the right choice.

And make the PCs care about his or her approval beforehand.
