I love Tibetan Mastiffs, and who really is hurt if we say it's a lion? And this, children, is the ferocious lion of Africa! Now, it's time for us to take our terrifying panther out for a walk — on a leash! — around the neighborhood.

Dianna Hanson was volunteering at Cat Haven sanctuary in Dunlap when she was tragically attacked after getting into the male lion's cage.Is that the right use of "tragically"?
You didn't provide a [sic] in your title.Why? I aim to disturb. Why do you think you shouldn't be disturbed? Also, "whom were striving" is bad English. And speaking of women and "warm... young people," why did the warm young persons David Foster Wallace (is 46 young?) and Aaron Swartz hang themselves in such a way that their wife/girlfriend would discover their hanged bodies? Why are they considered "warm" when they did that? Are you more disturbed now?
It’s possible that the word "tragedy" stems from the ritual sacrifice of goats. However, there is also evidence that the word arose because the chorus sounded like the song of goats — much like a current internet meme that matches popular songs to bleating goats. However, people aren't goats (which is precisely why the internet meme is funny and your ham-fisted question is not) and lions aren't known to perform acts to large numbers of fellow lions in order elucidate concepts regarding emotion. Therefore, the action at issue is not a reversal of whom was sacrificed but rather whatever action of hers led to her death. The nature of that action is unknown.
In any case, Aristotle seems a fair place to assess whether the performance of a deed merits the adverb and the answer is yes. The deed was important. It was complete. It had great magnitude. It evoked pity and fear. There is also substantial evidence that she used her acts during the internship to effect, in a broad audience, a relief from those emotions.
Ah. The question is reminiscent of ones asked daily in Freshman Comp. Good Times. Good Times.
A more interesting question is why you repeatedly make frigidly flippant remarks immediately after the deaths of warm and valuable young people whom were striving to effect positive change: David Foster Wallace, Aaron Swartz, and now this woman. It's disturbing.
