In one story, I have two characters who are animals that can shapeshift into humans. One is a lion, the other a spotted hyena. Both have grown up with their respective animal species and only recently gained the ability to become humans. My question is, both lions and hyenas can do some things that seem very cruel from a human perspective. For the lion, since he's a male, he'll be trying to get established as a pride male, and he'll kill any young cubs belonging to other males. For the hyena, she has a twin sister, and very young hyena cubs have vicious sibling rivalry right after birth, which she mostly won and ended up being bigger and stronger than her sister as a result. Both lions and hyenas will also steal kills from weaker animals such as cheetahs. How do I portray this natural cruelty without turning off my readers and making them dislike these two characters?
