Yes, I would treat the mother with compassion Then you’re defending someone that has done something so unbelievably cruel
That's not even a logical chain of thought, Josico. Treating someone with compassion self-evidently doesn't automatically equate to defending them. And you simply don't know enough to know that the was someone that has done something unbelievably cruel. If, for instance, she had a severe mental illness or learning difficulty she would have been unable to form the intention to be cruel.
This baby survived by pure chance of being found! It was not likely that someone would stumble upon it stranded in a children’s playpark after 10pm
And yet the baby was found, very quickly. Perhaps whoever left the child there knew that actually that was quite a busy route even at night time?
The mother left it without any regard for its life
Again, you don't know whether it was the mother who left her, or what steps she took to ensure her child's survival.
Why do you keep referring to this baby as "it"?
