Unknown movie about a Christian couple who is found dead by their son at their own place ?

Some years ago Hallmark had this movie going on about a Christian
couple who adopted 3 boys over the years.

The movie begins with one of the boys finding his parents killed at
their own house, and the story just goes on with telling the life of
the couple up to their death.

Something about the father was beating up the first adopted kid, and
the second adopted kid was kind of a nerd and always listened to what
their parents were telling him. The third adopted kid was very young
and like the second one always was listening to what his parents would
tell him to do.
the movie reveals at the end that the second adopted kid was the one
who killed his adoptive parents because he couldnt take the bossing of
his father anymore and so he faces a trial where a friend of his
adoptive family is helping him out as a lawyer.

I just can't remember any names of the characters or anything about
the title.
I really want to see this movie again because i thought it was very
interesting.

I would appreciate any form and kind of help !

Take care y'all ! :)
