Mkuu, I think victim ni yule ambae ameshindwa kabisa kujitoa, na hata hashtukii hali yake.
Survivor ni yule ambae yuko katika hali ya kua abused but is struggling to get out of it
Everyday is a survival day, with hope that ipo siku atatoka, or she/he has gone beyond and has actually ended the violence kwa njia moja au nyingine.
The terminology was probably adopted to challenge the 'victims' ili waelewe kua a shift in mentality means a shift in situation. A victim is not in control, a survival is.
