I'm desperately confused as to what you mean. If you think that hailing them as the heroes they are is in some way insensitive to their relatives, then I'm not very sure what planet you're inhabiting.
Personally, my view is that those widows and children would find what you said far more insensitive, namely that they died "forgetting that they weren't superheroes with special powers". Your wording is the insensitive one here: suggesting that they died in a fit of egotism belittles, trivialises, and completely misrepresents the sacrifice those brave, brave souls made, and casts them in a negative light that they in no way deserve.
