What if it IS what my character would do?

Is that scenario even a case where the player sticking to their guns "breaks" things? IMO, it seems like there's not a problem if they fight the slavers. Either:
* They lose and die - in most campaigns, a thing that can sometimes happen
* They lose and are KO'd - just pushes the issue down the road, but if any rescue or breakout opportunity is going to happen, down the road might be enough.
* They win - and the campaign continues down a different path

I'd say that even having a plot where "fighting back against being enslaved" ruins things speaks to a rather high degree of railroading.
