If they're caught i'd be surprised if anything happens to them
I watched a news article on wednesday about a woman that had put some puppies in a suitcase and left them to die, there was outrage at her but looking at her she obviously had mental health problems, I believe her sentence was 16 weeks in jail.
Now what she did is unthinkable but there have been people that have commited worse crimes against human beings and haven't been sent to prison
here's an example of a man that kicked his wife to death and walked free with a suspended sentence for manslaughter.
During her relationship with her husband, Malcolm, Sara Thornton endured repeated beatings. She sought help from numerous agencies, called the police repeatedly and her husband was eventually charged with assault. But he died before his court appearance. As he lay drunk on the sofa one night in June 1989, she stabbed him to death. The following year she was convicted of murder and given a life sentence by a judge who said she could have simply "walked out or gone upstairs".
Thornton became a cause célèbre for feminists campaigning against domestic violence. At the time, as the judge's comments made clear, little was known about what drives a battered woman to kill her abuser. Thornton appealed against her conviction, arguing that she killed as a result of "slow burn" provocation. She lost.
Two days later, Joseph McGrail killed his common-law wife, as she lay drunk, by kicking her repeatedly in the stomach. He was given a two-year suspended sentence for manslaughter and walked free. The judge expressed "every sympathy" for McGrail, adding "this lady would have tried the patience of a saint".
