What should be done to a woman who pours acid on a teenager for dating her husband 

This photo was sent to a media outfit by a reader who narrated how this girl, who is said to be just 19-years-old, was bathed and disfigured with a dangerous substance suspected to be acid, by a jealous wife because she was dating her husband.

According to the report the girl, a student of a tertiary institution, was having an affair with the married man who was spoiling her silly until the wife got wind of the affair, traced the girl to her home, and poured the substance on her.

Was the wife right in taking this extreme action? What should be done to her?
