rücksichtslos vs hart
hard
'hart' and 'rücksichtslos' can both describe negative behavior. 'hart' means that someone reacts in a strict, uncompromising, or not very friendly way. That can sometimes be necessary or meant matter-of-factly, for example in a difficult decision. 'rücksichtslos' is more strongly negative: a 'rücksichtslose' person does not pay attention to other people and their feelings or safety. So you can be 'hart' without being 'rücksichtslos'. Use 'rücksichtslos' when someone deliberately or thoughtlessly disregards others.
rücksichtslos
Der Fahrer war rücksichtslos und fuhr viel zu schnell durch die enge Straße.
The driver was reckless and drove much too fast through the narrow street.
hart
Der Lehrer war hart in seiner Bewertung, aber er erklärte jeden Fehler genau.
The teacher was harsh in his grading, but he explained every mistake in detail.
