Let me clarify what I intend to discuss with this post. Please do not take this too seriously, as Spiral Knights was never meant to be a serious game.
Throughout the game, Knights are put in a lot of combat encounters that they're supposed to get through by eliminating all their enemies which in almost every instance are already hostile to knights. But there are some cases where knights do not face entities that are outright hostile to them, and whether or not knights eliminate them is entirely optional. However, in terms of game mechanics, not elimaniting them is discouraged because killing enemies almost always drops loot while sparing them doesn't reward knights in any way.
For the sake of the argument, I'm not going to consider all those situations where knights are forced to eliminate enemies in order to progress with their adventures such as when a door requires all enemies to be defeated. Here I want to tackle situations where knights can make meanigful choices, not scenarios where the only way out to a more "peaceful" approach is to "leave the party" (or "not play the game") or to just "let the enemies kill you instead".
Let's start with the matter about killing Gremlin Knockers (link: https://wiki.spiralknights.com/Knocker ). In this case the action of knights are pretty much justified, because they are hostile enemies and they do not change behaviour when low on health. However, one of the issues I've thought is what if they were actual Gremlin children sent to fight knights; see, the game never confirms or disproves how old these enemies are, which can change your perception when they are elimated. If they are actually gremlin soldiers that just happen to have that kind of body, then this issue does not hold; however in the worst case scenario they might be young Gremlins sent to the battlefield without knowledge about what they're actually doing, indoctrinated by some Gremlin propaganda or even forcefully against their will.
Next is the issue about killing healers, which are Gremlin Menders and Silkwings. To make things a little bit more intersting and a little bit more fair, let's say that healers are the only enemies present in a given situation, and there are no Gremlins that can be revived by a mender. In this case these creatures cannot damage knights in any way, and thus can be left alone without worry. The main counter-argument against the fact that killing them is a somewhat immoral choice is that previously they were supporting hostile enemies, so they are indirectly hostile to knights and thus taking them out is acceptable. And to that, I'd like to add that the game almost never puts knights against a group made only of healers.
The main issue here is whether or not killing creatures that cannot directly harm knights is immoral, when they also do not have hostile enemies to support.
Following up is the debate upon the elimination of Yesmen and Pit Bosses while there are no overtimers or other devilites around. In this case, these creatures cannot harm knights (just like healers) but do not support other hostile enemies as well. Is the act of killing these sort of enemies (when no other devilite or enemy is around, mind you) immoral ?
Last but not least (even though it is not very instersting), is killing Mewkats (https://wiki.spiralknights.com/Kat) and Love Puppies immoral (when you can make an actual choice of course)?
For this one I'm going to take a side and say that yes it is. I dare say that most Mewkats deaths are actually accidents or were dictated by some stupid door that wants all enemies dead.
I'm curious to hear about what other fellow knights have to say on these matters.
I'm surprised that people haven't engaged with this thread. In the past, we have had popular threads discussing our "invasion" of Cradle, whether we are actually the good guys, etc.
Many video games, including this one, are based on the idea that violence solves problems. I would love to hear more discussion of how knights can be incentivized to use only as much violence as necessary.
To some extent, these incentives changed for me when elevators became free (2013-07-30). Before that update, I wanted to extract every crown from each level, so I killed every last monster. After the update, I cared more about crowns per time. I speed-ran more. I skipped unforced fights. In this way, I was incentivized to kill only when I had to.
But when you skip unforced fights, new tactical problems arise. I found myself thinking, "How do I avoid getting trapped by this huge crowd of monsters that is following me?" And "How do I get out of the AI radius for those scuttlebots as quickly as possible?" So the game changed in interesting ways that have nothing to do with morality.
