Sure, he seemed like he just wanted a real estate empire, yet you just have to look at how he wanted to achieve that and his whole ethos was summed up in this exchange:

This has become very prevalent with Batman villains over the last 30 - 35 years. I think it works with characters like Two-Face and, after the great revision by B:TAS for Mister Freeze. Other Batman villains should just be complete evil or thieving b@stards. 

I’m really at a loose end to think of the last time there was a villain who was just out and out evil with no sympathetic shades in their background / origin.

That's one aspect that never sat well with me. I f Harvey is already suffering from mental health issues, and commits crimes before he becomes Two-Face, then it really erodes the tragedy and sympathy you should have for the character, and negates stories (pre this revelation) where he tried to rebuild his previous life.

Much as I hold B:TAS in high regard, Big Bad Harv was one of the few missteps they really made.

When I read this comment, I was reminded on the Bugs Bunny / Marvin Martian cartoon where both characters are on Mars, and there's a gumball machine: "10,000 Instant Martians - Just Add Water."
