Car starts without key when jumped

[Electrocuted]

95 toy corrolla

I jumped another car and it killed the battery on my car. My car ran for a while after being jumped back to life after that then died on its own. Second time I jumped it it sparked like crazy and started without the key even in the ignition and then died again after a while cause tyhe battery was unchargable (had it tested). I'm kinda scared of it now but I need to install a new battery. Is the ignition stuck to on because the battery died? Any fuse I can remove or something to prevent the sparks when it tries to start without the key? Thanks in advance.

hello, it sounds like it may have been jumped backwards(any chance???)
i'd check the main box under hood for blown fuses/links
