An idiom that captures that situation (reckless free sex, no condom, and then contracting HIV AIDS and died young) would lean on the idea of carelessness leading to severe consequences. A few that fit well:
- “Play with fire, get burned.” → Taking risky behavior invites serious consequences.
- “Reap what you sow.” → You face the results of your own actions.
- “Dance with the devil.” → Flirting with danger brings destruction.
- “Ride bareback and pay the price.” (informal, slangy, directly alluding to unprotected sex).
- “Sow your wild oats, choke on the harvest.” (extended play on the traditional idiom).
