The word "ruthless" is too of a strong word to describe Garrus' morality and personality. I can, however, see why some people would consider Garrus a "ruthless" type of guy.
For example in ME1, when a few hired thugs are assaulting Dr. Chloe on the Citadel, we see outright the inklings of his morals; he is quick to fire on these thugs even when they have a hostage, which shows that he is willing to put others in jeopardy and outright break the rules to uphold this sense of true justice. He took a risk at that situation. Garrus even states himself that he would enjoy living with no rules or restrictions, that he would bring more criminals to justice without the bureaucracy blocking him.
His actions in the first game are mostly reflective on your conversations with him. You can also by his conversation say that he is "ruthless" towards enemies and anyone trying to go above the law. This can be seen by when doing the Saleon mission. If you Saleon is killed outright, it impresses Garrus more in the short term; that evil can be squashed if you are just and decisive. Yet again showing that any means are necassary to achive justice.
Garrus is quick to act in extreme situations, not thinking about the consequences or his own well being when pursuing an enemy. Even Urdnot Wrex, which I would consider more "ruthless" than Garrus, goes as far as to coomed Garrus for this quality (though he berates him more for it).
PS. You don't have to be ruthless to be a ladies manB)
