oh, we're having ethic class here? noice!
i mean, yeah. in some WN i read, lots of MC overhunt a certain type of dangerous monster, overmine certain rare metal, or overnurture either slaves or commoners life.
none of them realize that ecosystem is a thing, it's like they expect every resources is infinity. and giving someone a huge powerboost overnight could oftenly result in arrogance.
this is what ethic is about, to understanding one action could lead to a certain consequence.
but creating a breakthrough in technological advance is a different thing entirely, like imagine in a world where you can only send message using pidgeon but then suddenly this reincarnated person inventing a smartphone. some people might horrified and think it would lead to information war.
technological convertion is never an easy thing, when first steam engine invented, most people suspect a supernatural at work, when first photography is invented, people suspect that photograph is something that suck your soul.
but alas, most of the time, advancement is necessary, human can travel much more distance in shorter time, sending information quicker, and even prevent death and increase life expectancy to double their current average lifespan.
so, yeah. it's really nice if more author actually mention about this.
