However, the reasons aren't what really matter. What matters is the consequence.
If the consequence for Good or Evil is all that matters, why would you not then make sure that the consequences of your actions are what you want them to be, Good or Evil? So make sure that the consequence of killing the OP's troll is good or evil (through this i've become unsure as to the Lawfulness of the act, but am still convinced as to the Evilness). Which would take some understanding of why the troll killed the orcs and thus aided the party. And I've always left open the possibility that you might still need to kill the troll anyway.
I feel that you are talking about: The ends justify the means. If the end is good then it is Good (and given what we know of the situation we can't actually say that the city we just torched is Evil)If a Troll of unknown alignment joins combat between a Good party and any other creature, and, during that combat is slain, the Good party is effectively "torching the Evil city with slaves in it". It is for the betterment and protection of a greater number of Good persons than it harms.
I'm talking about about: The good will not lower themselves to some means to achieve their goals, while the evil are happy with the means if they get to the ends they want.
I'd argue that Law/Chaos is not the axis being used here but Good/Evil. Any alignment could want to destroy the bunker for a variety of reasons.To bring this into a real world scenario that might be easier to understand for some, assume a tyrannical dictator holed himself up in a bunker with twelve of his trusted, also tyrannical allies (generals, scientists, or what-have-you), and one benevolent, altruistic scientist who is being held hostage. It is still a Good act to destroy the bunker and thereby everyone in it because it is for the betterment of the greater Good. Killing the good scientist is regrettable, but necessary. It is Chaotic Good to destroy this bunker. It is Lawful Good to send a strike team to extract the good man and kill the evil men with more precision tactics.
For a LG/NG/CG person/group, they would want to do so after saving the hostage. If they couldn't save the hostage then some might decide the collateral damage does not aid the greater good (and try something else) while others would destroy the bunker but feel bad for the hostage while others would say it was a necessary evil and sleep well.
I'll answer this but remember that "Always Evil" is different to "usually Evil" (i.e. for the former the motivation is likely be more self centered than to offer aid altruistically) in an "SRD" world.My question to you is this, if a Red Dragon flew overhead and torched half of your enemies in a combat, landed and proceeded to torch things (other than you), would you attack that Red Dragon?
Few of my Good to Neutral PCs would blindly attack a Red Dragon in such a situation. They'd wonder what is going on (as you mentioned before, PCs know that alignment guarding spells/items are available, so are polymorph, illusions, geas/quest, divine intervention, etc thus things are often not what they seem).
Options for them:
(besides not getting too close to the dragon just in case
- Be careful not to include RD in areas of effect, but continue the fight
- not continue but watch the fight
- just run away (not likely to get far though),
- prep for battle with a red dragon and then talk (and maybe then fight).
Battling the RD right away (or after prepping) would only occur for Evil and maybe N/CN (unsure of LN) PCs seeking to gain advantage (hey, dragon armour).
