When used as a verb regard means:
- consider or think of (someone or something) in a specified way.
While when used as a verb consider means:
think carefully about (something), typically before making a decision.
"each application is considered on its merits"
•think about and be drawn toward (a course of action).
"he had considered giving up his job"
•regard (someone or something) as having a specified quality.
They have a lot of overlap in there usage and can be considered synonymous in most situations.
Or as an answer in this post said before: "Consider" vs. "Regard"
"Consider" has a general connotation that logical evidence is being weighed.
"Regard" is used in three senses. It can be used when popularity or reputation is a big part of the conclusion reached, as in "He is held in high regard" or "the court regards this as..." (since court opinions are the accumulation of precedents). It can also be used when emotion or sentiment is involved, as in your example where somebody is regarded coldly. [
The third is the "particular way" that LongMan described.]
Hopefully I made this as clear as possible!
