Gas stove you mean…
A hammer may be used for purposeful destruction as easily, although it's performance for that would be much lower and require more skills.
you can burn a house down with an electric with minimal ingenuity
Electric heating elements tend to die pretty quickly, if you exceed the allowed temperature. Also, the controllers, automatically switching them off, are easier/cheaper to implement than with the gas.
OTOH, I don't claim they're no more dangerous than a rubber duck…
we all know nothing is safe; if you have to rub someone out in theory you could grind up a chalkboard eraser and feed it to them (and feel free to look into where THAT analogy element was stolen from, good luck). but as you said, it's not as safe as a rubber duck.
hammers are a lot closer, esp in terms of unleashed tools of destruction like 'fire' hidden within it that grow without attendance under the right circumstances
if you can get an easy, obvious snowball rolling (or fire started) with it, it's not a simple tool, is my rough thinking here
A bunch of technomancers in the fediverse. Keep it fairly clean please. This arcology is for all who wash up upon it's digital shore.
