The basis of the skill is close to what Caster Eli has which is 「無辜の怪物」. I would say the english language is probably somewhat limited when trying to translate 'accurately' especially when it comes to Japanese origin terms. So I think it is better to leave it as monster, disaster would give a different meaning afterall.
