Yes bro, I feel where you are coming from but the best thing to do is improve yourself and become an example to the rest of your family... maybe not having a male figure has damaged you but then it would also have effected your sister too... perhaps she is seeking comfort from strange men because she does not find it at home? It happens. Anyways bro, like others have said and will say , just improve yourself and when the family members see the change, they will also change

That's probably the best course of action

And Allah knows best
