Chris Hemsworth is definitely looking out for his little brother Liam, but when it comes to the 'Hunger Games' star's "reckless" personal mistakes, he will not show any sympathy because they are just so alike.

Hemsworth has no sympathy for Liam's failed relationships

While speaking with the January 2015 issue of GQ magazine, the 31-year-old actor opened up about having a protective nature over his famous lil bro, and how becoming a family man has changed his livelihood.

"I've watched Liam do things I did at his age," he told the magazine. "Like being in relationships he shouldn't be in, or being reckless just to prove a point. And I had no empathy. My mom had to remind me I was the same way."

Chris may be referring to the day after Liam broke off his 15 month engagement with Miley Cyrus in September 2013, when he was photographed kissing and embracing Mexican actress Eiza Gonzalez in Los Angeles.

The 'Thor' star recalled how his lack of commiseration towards Liam is very similar to the way his older brother Luke, 34, treated him. "Back when I was still on the soap [Australian series Home and Away], I became incredibly insecure and full of anxiety because I didn't know if I was any good," he explained. "Yet I wanted it so bad. I spent years being angsty, constantly telling people I wasn't just part of a soap opera, that I was a real artist. And I remember Luke sort of snapping, telling me to shut up, that he was sick of hearing it."

As well as speaking about his siblings, Chris also discussed his family life with wife Elsa Pataky, and their three children, daughter India, 2, and twin sons Tristan and Sasha, 8 months. "The fame, the parties, the women -- I did that stuff back home," he recalled of starring on Australian soap 'Home and Away.' "I got away with a lot more over there. Then I came here and sort of started over."

Now Chris admitted his biggest worry about fatherhood is "just not screwing it up."
