Max Power:
Take comfort in the fact that the model you ripped apart was one barely worthy of being built in the first place. The old Hobbycraft Dash 8 was a disapointment to all modelers with all but the most passing familiarity of the type. I still keep hoping a proper 1/72 Dash 8 will be molded one day, and a Dash 7 to go with it.
As for my own aggressions taken out on kits:
I smashed up a Hasegawa 1/72 Mitsubishi Mu-2 once.
I was at the kitchen table working on it and trying to make an important phone call. I had the local yellow pages to one side of my work space and was working on the kit's wing tip tanks, which were just about the most ill engineered tip tanks I've ever encountered (both are divided into six sections!), between trying to get through on a constantly busy phone line.
The tip tanks were just shy of impossible to properly align lengthwise because of the overdone parts breakdown and were really starting to grate on me.
I picked up the phone and tried again and finally got through only to be told that the person I needed to talk to, who knew I'd be calling and knew it was important, had called in sick that day and there was nobody else in the office to help me! That did it!
I slammed the phone down as hard as I dared without breaking it, picked up the yellow pages and slammed them down, hard as I could, on my model. Totally demolished beyond hope, but I felt better for it.
As I said Max, don't feel bad, much better kits in your stash survived because of your Dash 8's selfless sacrifice to appease your anger that day.
