Why was the eviction notice served? I find that is an important detail, since it is highly likely that it was served because the father was unable to pay, due to unemployment, illness or similar. (Highly likely because of his history with mental illnesses.) This is important, because if a constellation like that was the root cause, then the fault (not the legal, but the ethical fault) lies with the government system failing to provide basic necessity of life payments to less fortunate members of their society; resulting in the father feeling pushed so much into a corner that he felt the need to defend the home over his family's heads with violence.
