1995 Jeep Cherokee I ruined something electrical

I left an interior light on in my jeep. I tried jumping it with a 50 amp quick start charger. Now it won't start and the hazard lights blink when I try charging it with a normal charger. I took the battery out and put it in my car, it's new and works perfectly

interior and headlights come on in the jeep but when I turn the key it doesn't do anything. Once in awhile it'll click, but mostly it's just dead.
