Nurkasih,
I'm not even going to dignify some people's post with a response

Killing animals outright without even trying other humane ways first is just inexcusable, however way u see it.
No anjing is zalim, no babi is zalim either. They are not capable of being 'zalim' or of having malicious, vindictive intentions (unlike us humans). Neither are they capable untuk 'buat dosa'. They were just hungry, confused animals who have not been given food due to the closure of the farm due to police investigations.
If somebody had had enough forethought to feed these poor pets their daily meal, they wouldn't have had to kill all those farm animals as a source of food and maybe none of this had to happen.
Kudos to Perhilitan for rescuing the birds after knowing of their existence. I only wish somebody had done the same for these poor dogs.
