Most wild hogs would rather run than fight, but there are exceptions.

Domesticated Hogs can also be dangerous, notional and have little fear of humans.

I dated a girl whose father owned a hog farm. He warned me about certain hogs, which ones to avoid. Some where friendly, some weren't.

I watched a Sow with piglets, in an outside pen, eat a four foot Timber Rattler. This Rattler was at lest 12 inches in diameter. The Rattler struck at her a couple times, she bit it once and swallowed it pretty much whole, jiffy quick, chomp, chomp, chomp and it was gone. I was astounded. I was thinking of running to my truck to get my shotgun, but she took care of business before I could even react. The bites didn't seem to bother her any.
