HFTs tend to add liquidity when it's least valuable, and they tend to consume liquidity when it's most vital.
For example, an analysis of the 2010 flash crash shows it was worsened by HFTs fleeing their positions once volatility increased, which is the exact time that liquidity and market-making are most valuable.
If there is any social benefit to HFT it is utterly trivial.
