I (28M) took over my dad's business about a year ago since he passed away. 

It's only a mid sized business. Not at millionaire status or anything but well into six figures at least. My dad treated it like more of a ''caring'' approach to it I guess? Not sure how to describe his attitude about it really, he was just really content and loved life I guess. He liked his business the way it was, and he was good friends with many of the the owners of the local ''rival'' business.

I have wanted to take a different approach to it. I want to win, basically. **I want to destroy my competitors**, I have no delusions of grandeur in that I expect to become a multi-millionaire (so I'll get that out of the way), but I can definitely see a lot of potential for growth. I want them to go out of business and expand.

So I went for a drink with my sister (24F) and mother (55F) and we had a few drinks. Anyway they ended up asking me about how I feel about taking over that business and whether if that's really what I wanted to do, and I said yes, I then said while a bit drunk ''I want to destroy the competitors'' (well, I actually 'I want to destroy___ and then said the actual names of the local rivals, but I can't say those names here). 

They said I was a huge asshole for having that mentality. But I don't see how....I mean I dabbled a bit into Competition Law once while I was a at uni, and I found myself liking the Chicago school of competition more than the alternatives (e.g. Ordoliberal) but my sister especially went in on me. She said that my mentality is ''toxic'', AITA?
