A girl striped naked after slashing bff with a razor on the face

In Benue state a girl used a razor blade to slash bff/neighbor's face. This was the result of a quarell between the to girl. The one who did the slashing and whom we will call girl 'A' accused the one slashed whom we will call girl 'B' of snatching her suger daddy (a boy friend that is a lot older than the girl and take care of her financial needs as along as she satisfies his sexual needs). She said she had found out that girl 'B' slept with her suger daddy. She also said she had just introduced her man to girl 'B'. So when she confronted 'B' about it a fiece argument broke out. It got worse as the neighbors were all attracted to the verbal fight.
But girl 'A' crossed the line when she got physical. She attacked her bff with a razor blade, slashing her face. Blood was everywhere. It was a really gory site.
When the other neighbors saw it they attacked 'A'. The infuriated mob beat and stripped her. This was one of the many jungle justice common in Nigeria
Do u think it was the right thing to do or should they have done something else?
