If a family member hurt you do you think they change or they are the same

So for each family it's different levels of chaos and family drama and family abuse and different kinds of abuse like financial, emotional, mental, physical, sexual, negligence, abandonment, ignoring. There's all these dangerous things and bad things like if a relative beat you with a belt would they change in the future or still have that possible outburst? It's confusing because you are supposed to love family and trust them but it's like can you really trust them it's like flashbacks of this person and you remember how they treated you and you are afraid what about like the other family kids will they be that same person they were or be a better person
