The Catholic Church has no adherents to domestic violence. The assignment is fictitious.

Jess,

The Catholic Church is opposed to domestic violence, see for example:

• Intervention of Archbishop Silvano M. Tomasi, Permanent Observer of the Holy See to the United Nations and other International Organizations in Geneva from the 20th Session of the Human Rights Council (18 June to 6 July 2012)
• Message of His Holiness Pope Francis for the Celebration of the Fiftieth World Day of Peace, 1 January 2017 - Non-violence: a Style of Politics for Peace

You can get other references by doing this search on Google:

site:vatican.va "domestic violence"

Be sure to include the quotation marks.

This is a topic that, as you allude to, is covered by other teachings on violence. You won't see too much elaboration on the sin of domestic violence because it's so obvious that it's wrong, but you will see numerous negative references to it.
