I explained why in the follow up comment but I'll clarify. There's obviously a spectrum: GOOD (morality) BAD (immorality). Then there is by default PERPETRATOR (the BAD deed actor) VICTIM (the SUFFERER (that we essentially view as VICTIM) of the act.

The EVENT/ACT which we are deeming/judging (from PERSPECTIVE of OBSERVER) as BAD is ultimately determined by how each SUBJECT is placed on that spectrum. THE ACT alone can't be judged on this spectrum unless those two parties are realized.

LION attacking/destroying CUB (of rival) is THE ACT. So the natural sympathy which we have for VICTIM is how it ultimately exists within the confines of SUBJECTIVITY. Because conversely, to have sympathy for perpetrator is essentially deemed again to be immoral.

OBJECTIVELY it was one life form ending another life form. PHYSICALITY: matter interacting with matter. Energy transforming.
