You’re definitely sinful for what you had done! Being this violent is not normal, you must sincerely repent to Allah and must control your anger and leave the place immediately before it escalates to this level.
Ask sincere forgiveness from your sister even if it was her fault to begin with, what you have done is totally unacceptable. If you want Allah to forgive you and to ward off this curse, you must seek forgiveness from her immediately.
