Very few tools are good or evil. (I say “very few” because there are outliers – the guillotine might be all evil and penicillin is pretty much all good.) You hold them. You need a compass.
…no, the other kind. The moral kind.
A tool can’t define whether you’re good or evil. Valor and virtue don’t come from using certain objects or not using other ones. Discretion and application guide the soul.
