that is part of nature mystic
and there is really no like or dislike about it as it balances itself out
whereas man puts the balance out
in nz man(woman included, lets share the blame) brought many animals etc to this country that are now problems
he brought rabbits for food, fur and as pets , no predators for rabbits here just the odd hawk and falcon
rabbits (surprisingly) bred like rabbits so he introduced mustelids to control them naturally, everyone had jobs back then no time to go shoot rabbit
the poor old native animals had no chance as they hadn't had to deal with a major ground predator before and are easier pickings than rabbits, no contest
as an example the nz and australian brown quail are taxonomically almost the same bird, the nz brown quail is thought to be almost extinct whereas the australian one is still running around nz
the possible reason is the nz quail when approached would sit still and wait for you to walk over and pick it up, easy pickings
whereas the aussie quail when approached too closely will startle and take off
2 different reactions the aussie bird evolved with a lot of ground predators with a keen sense of smell, the nz ones evolved with no ground predators (maybe the Weka) so didn't need to run
so man mucked up the balance and man needs to fix it though it is probably too costly to do nowadays
even one pregnant mustelid left is one too many
