The blame is shared tbh.
1. A child of that age should not be able to circumvent the security - a basic few foot transparent plastic guard to prevent anybody young/falling into the enclosure would all that would have been required to prevent this.
After this only adults would be able to who are responsible for themselves.
2. The parents obviously were not paying sufficient attention at the time being.
The choice the shoot the animal was out of need & self-preservation - had they not acted in that way & the animal decided to kill the child they would all the out of a job.
Had the two preventative measures been taken above there would have been no need.
