Carl Grimes, the young son of series protagonist Rick, sustained a bullet wound to the head in a recent issue of the comic.
Adlard told The Daily Blam: "Of course the [television] show should put children in jeopardy [too]. I think that's a given. Otherwise, what's the point in having those characters there?"
The artist dismissed the suggestion that it was "particularly brave" for either the Walking Dead comic or the TV version to place younger characters in peril.
"It's just a product of good, logical storytelling," he argued. "Anything else is just a cop out."
The Walking Dead creator Robert Kirkman previously admitted that he would be reluctant to have Rick (Andrew Lincoln) lose his right hand on television, as happened in the original comic.
"When I'm writing a comic book, I don't think about what I'm doing," he explained. "I go, 'Oh, it'd be pretty cool if they cut his hand off right now. That'd be pretty shocking, right?'
"Then I do it, and five issues later, I write 'Rick opens a can of beans' and then I look at the script and think 'He can't do that now'. I didn't even think that through."
The Walking Dead will return to AMC in the US and FX in the UK in October.
